This way we avoid having hundreds of relays working at the beginning of each month but none still up by the end. Just divide your monthly amount by For example, if you have 50 GB to offer each way, you might set your RelayBandwidthRate to KBytes: this way your relay will always be useful for at least half of each day. But there are a few exceptions:. If you open your DirPort, then Tor clients will ask you for a copy of the directory.
This probably accounts for most of the difference between your "write" byte count and your "read" byte count. Another minor exception shows up when you operate as an exit node, and you read a few bytes from an exit connection for example, an instant messaging or ssh connection and wrap it up into an entire byte cell for transport through the Tor network.
The parameters assigned in the AccountingMax and BandwidthRate apply to both client and relay functions of the Tor process. Thus you may find that you are unable to browse as soon as your Tor goes into hibernation, signaled by this entry in the log:. The solution is to run two Tor processes - one relay and one client, each with its own config.
One way to do this if you are starting from a working relay setup is as follows:. Each Tor relay has an exit policy that specifies what sort of outbound connections are allowed or refused from that relay. The exit policies are propagated to Tor clients via the directory, so clients will automatically avoid picking exit relays that would refuse to exit to their intended destination.
This way each relay can decide the services, hosts, and networks it wants to allow connections to, based on abuse potential and its own situation. The default exit policy allows access to many popular services e. This setting means that your relay will be used for relaying traffic inside the Tor network, but not for connections to external websites or other services. If you do allow any exit connections, make sure name resolution works that is, your computer can resolve Internet addresses correctly.
This tells Tor to avoid exiting through that relay. In effect, relays with this flag become non-exits. Please reach out to the bad-relays team so we can sort out the issue. Several countries, including China and Iran, have found ways to detect and block connections to Tor bridges. So should you run a normal relay or bridge relay?
If you have lots of bandwidth, you should definitely run a normal relay. Thanks for volunteering! Note: As of Tor 0. Eventually they will replace the old RSA identities, but that will happen in time, to ensure compatibility with older versions. As of Tor 0. In simple words, it works like this:.
If you want to use this feature, you can consult our more detailed guide on the topic. If you want to keep using the old key, see the Upgrading your Tor relay FAQ entry for how to restore the old identity key. A service called Tor Win32 Service will be installed and started. This service will also automatically start every time Windows boots, unless you change the Start-up type. An easy way to check the status of Tor, start or stop the service, and change the start-up type is by running services.
Optionally, you can specify additional options for the Tor service using the -options argument. The uninstaller is currently not capable of removing the active service. Competent vserver admins are able to configure your server to not hit these limits.
Look for "failcnt" in tcpsndbuf, tcprecvbuf, numothersock, and othersockbuf. Ask for these to be increased accordingly. Xen, Virtual Box and VMware virtual servers have no such limits normally. If the vserver admin will not increase system limits another option is to reduce the memory allocated to the send and receive buffers on TCP connections Tor uses. An experimental feature to constrain socket buffers has recently been added.
If your version of Tor supports it, set "ConstrainedSockets 1" in your configuration. See the tor man page for additional details about this option. Unfortunately, since Tor currently requires you to be able to connect to all the other Tor relays, we need you to be able to use at least file descriptors.
We hope to fix this in the future, once we know how to build a Tor network with restricted topologies -- that is, where each node connects to only a few other nodes. But this is still a long way off. If you do decide to run more than one relay, please set the "MyFamily" config option in the torrc of each relay, listing all the relays comma-separated that are under your control:. That way clients will know to avoid using more than one of your relays in a single circuit.
Tor guesses its IP address by asking the computer for its hostname, and then resolving that hostname. Also, if you have many addresses, you might also want to set "OutboundBindAddress" so external connections come from the IP you intend to present to the world. See portforward. If your relay is running on a internal net you need to setup port forwarding.
Forwarding TCP connections is system dependent but the firewalled-clients FAQ entry offers some examples on how to do this. You may have to change "eth0" if you have a different external interface the one connected to the Internet. All of this said, fast Tor relays do use a lot of ram. It is not unusual for a fast exit relay to use MB of memory. The simplest example is an attacker who owns a small number of Tor relays.
There are also some downsides to running a Tor relay. It is an open research question whether the benefits outweigh the risks. A lot of that depends on the attacks you are most worried about. Exonerator is a web service that can check if an IP address was a relay at a given time. We recommend these non-profit charities that are happy to turn your donations into better speed and anonymity for the Tor network:.
Note that there can be a tradeoff here between anonymity and performance. At the same time though, economies of scale for bandwidth mean that combining many small donations into several larger relays is more efficient at improving network performance. Improving anonymity and improving performance are both worthwhile goals, so however you can help is great! Since the. Currently, the Tor directory server provides this look-up service; and thus the look-up request must get to the Tor network.
Therefore, your application needs to pass the. So, how do you make your application pass the hostname directly to Tor? This will allow you to use almost any program with Tor without leaking DNS lookups and allow those same programs to access onion services. Versions of Tor before 0. Starting with 0. The stuff in parenthesis is optional. Only one release is ever made with any given set of these version numbers.
The TAG lets you know how stable we think the release is: "alpha" is pretty unstable; "rc" is a release candidate; and no tag at all means that we have a final release. So for example, we might start a development branch with say 0. The patchlevel increments consistently as the status tag changes, for example, as in: 0.
Eventually, we would release 0. The next stable release would be 0. Why do we do it like this? Because every release has a unique version number, it is easy for tools like package manager to tell which release is newer than another. The tag makes it easy for users to tell how stable the release is likely to be. To set up your own Tor network, you need to run your own authoritative directory servers, and your clients and relays must be configured so they know about your directory servers rather than the default public ones.
Apart from the somewhat tedious method of manually configuring a couple of directory authorities, relays and clients there are two separate tools that could help. One is Chutney, the other is Shadow. Chutney is a tool for configuring, controlling and running tests on a testing Tor network. It requires that you have Tor and Python 2. You can use Chutney to create a testing network by generating Tor configuration files torrc and necessary keys for the directory authorities.
Then you can let Chutney start your Tor authorities, relays and clients and wait for the network to bootstrap. Finally, you can have Chutney run tests on your network to see which things work and which do not. Chutney is typically used for running a testing network with about 10 instances of Tor. Every instance of Tor binds to one or two ports on localhost Shadow is a network simulator that can run Tor through its Scallion plug-in.
Shadow can be run on any linux machine without root, and can also run on EC2 using a pre-configured image. Also, Shadow controls the time of the simulation with the effect that time-consuming tests can be done more efficiently than in an ordinary testing network.
The Shadow wiki and Shadow website are good places to get started. A fully Java implementation of the Tor client is now available as Orchid. We still consider Orchid to be experimental, so use with care. One is multithreading: you have a separate micro-program inside the main program for each net connection that reads and writes to the connection as needed. This, performance-wise, sucks.
And the newest ways are finally fast, but are not available on all platforms. However, On the the Win32 platform by Microsoft the only good way to do fast IO on windows with hundreds of sockets is using overlapped IO, which is grossly unlike every other BSD sockets interface. Internet communication is based on a store-and-forward model that can be understood in analogy to postal mail: Data is transmitted in blocks called IP datagrams or packets. Every packet includes a source IP address of the sender and a destination IP address of the receiver , just as ordinary letters contain postal addresses of sender and receiver.
The way from sender to receiver involves multiple hops of routers, where each router inspects the destination IP address and forwards the packet closer to its destination. Thus, every router between sender and receiver learns that the sender is communicating with the receiver.
In particular, your local ISP is in the position to build a complete profile of your Internet usage. In addition, every server in the Internet that can see any of the packets can profile your behaviour. The aim of Tor is to improve your privacy by sending your traffic through a series of proxies.
Your communication is encrypted in multiple layers and routed via multiple hops through the Tor network to the final receiver. Note that all your local ISP can observe now is that you are communicating with Tor nodes. Similarly, servers in the Internet just see that they are being contacted by Tor nodes. First, Tor prevents websites and other services from learning your location, which they can use to build databases about your habits and interests.
Because these relays are run by different individuals or organizations, distributing trust provides more security than the old one hop proxy approach. Note, however, that there are situations where Tor fails to solve these privacy problems entirely: see the entry below on remaining attacks. Yes, the guy running the exit node can read the bytes that come in and out there.
Tor anonymizes the origin of your traffic, and it makes sure to encrypt everything inside the Tor network, but it does not magically encrypt all traffic throughout the Internet. This is why you should always use end-to-end encryption such as SSL for sensitive Internet connections. First, Tor protects the network communications. It separates where you are from where you are going on the Internet.
What content and data you transmit over Tor is controlled by you. However, since you have logged into their sites, they know who you are. These binary applications run as your user account with your permissions in your operating system.
This means these applications can access anything that your user account can access. Some of these technologies, such as Java and Adobe Flash for instance, run in what is known as a virtual machine. This virtual machine may have the ability to ignore your configured proxy settings, and therefore bypass Tor and share information directly to other sites on the Internet.
The virtual machine may be able to store data, such as cookies, completely separate from your browser or operating system data stores. Therefore, these technologies must be disabled in your browser to use Tor safely. We produce a web browser that is preconfigured to help you control the risks to your privacy and anonymity while browsing the Internet.
Not only are the above technologies disabled to prevent identity leaks, Tor Browser also includes browser extensions like NoScript and Torbutton, as well as patches to the Firefox source code. The full design of Tor Browser can be read here. The Tails team has created an entire bootable operating system configured for anonymity and privacy on the Internet.
Tor is a work in progress. Further, the Tor client establishes an ephemeral encryption key with each relay in the circuit; these extra layers of encryption mean that only the exit relay can read the cells. Authentication : Every Tor relay has a public decryption key called the "onion key". Each relay rotates its onion key once a week. Coordination : How do clients know what the relays are, and how do they know that they have the right keys for them?
Each relay has a long-term public signing key called the "identity key". Each directory authority additionally has a "directory signing key". The directory authorities dir-spec. How do clients know what the directory authorities are? The Tor software comes with a built-in list of location and public key for each directory authority. So the only way to trick users into using a fake Tor network is to give them a specially modified version of the software.
Tor like all current practical low-latency anonymity designs fails when the attacker can see both ends of the communications channel. For example, suppose the attacker controls or watches the Tor relay you choose to enter the network, and also controls or watches the website you visit.
In this case, the research community knows no practical low-latency design that can reliably stop the attacker from correlating volume and timing information on the two sides. So, what should we do? Suppose the attacker controls, or can observe, C relays. Suppose there are N relays total. But profiling is, for most users, as bad as being traced all the time: they want to do something often without an attacker noticing, and the attacker noticing once is as bad as the attacker noticing more often.
Thus, choosing many random entries and exits gives the user no chance of escaping profiling by this kind of attacker. The solution is "entry guards": each Tor client selects a few relays at random to use as entry points, and uses only those relays for her first hop. Restricting your entry nodes may also help against attackers who want to run a few Tor nodes and easily enumerate all of the Tor user IP addresses.
Tor will reuse the same circuit for new TCP streams for 10 minutes, as long as the circuit is working fine. If the circuit fails, Tor will switch to a new circuit immediately. But note that a single TCP stream e. Otherwise an adversary with a partial view of the network would be given many chances over time to link you to your destination, rather than just one chance. The actual content of these fixed size cells is documented in the main Tor spec , section 3.
We have been considering one day adding two classes of cells -- maybe a 64 byte cell and a byte cell. This would allow less overhead for interactive streams while still allowing good throughput for bulk streams. It holds open a handful of connections so there will be one available when you need one. An adversary with a great deal of manpower and money, and severe real-world penalties to discourage people from trying to evade detection, is a difficult test for an anonymity and anti-censorship system.
After seeing these attacks and others first-hand, more effort was put into researching new circumvention techniques. Pluggable transports are protocols designed to allow users behind government firewalls to access the Tor network. These attacks come from examining characteristics of the IP headers or TCP headers and looking for information leaks based on individual hardware signatures.
One example is the Oakland paper that lets you learn if two packet streams originated from the same hardware, but only if you can see the original TCP timestamps. Tor transports TCP streams, not IP packets, so we end up automatically scrubbing a lot of the potential information leaks.
Do not use a VPN as an anonymity solution. VPNs encrypt the traffic between the user and the VPN provider, and they can act as a proxy between a user and an online destination. A technically proficient attacker or a number of employees could retrieve the full identity information associated with a VPN user. Identities can be discovered by following a money trail using Bitcoin does not solve this problem because Bitcoin is not anonymous , or by persuading the VPN provider to hand over logs.
When you use a VPN, websites can still build up a persistent profile of your usage over time. When you use Tor the IP address you connect to changes at most every 10 minutes, and often more frequently than that. Proxychains is a program that sends your traffic through a series of open web proxies that you supply before sending it on to your final destination. Unlike Tor , proxychains does not encrypt the connections between each proxy server.
An open proxy that wanted to monitor your connection could see all the other proxy servers you wanted to use between itself and your final destination, as well as the IP address that proxy hop received traffic from. Because the Tor protocol requires encrypted relay-to-relay connections, not even a misbehaving relay can see the entire path of any Tor user. While Tor relays are run by volunteers and checked periodically for suspicious behavior, many open proxies that can be found with a search engine are compromised machines, misconfigured private proxies not intended for public use, or honeypots set up to exploit users.
As mentioned above, it is possible for an observer who can view both you and either the destination website or your Tor exit node to correlate timings of your traffic as it enters the Tor network and also as it exits. Tor does not defend against such a threat model. In a more limited sense, note that if a censor or law enforcement agency has the ability to obtain specific observation of parts of the network, it is possible for them to verify a suspicion that you talk regularly to your friend by observing traffic at both ends and correlating the timing of only that traffic.
Again, this is only useful to verify that parties already suspected of communicating with one another are doing so. In most countries, the suspicion required to obtain a warrant already carries more weight than timing correlation would provide.
Furthermore, since Tor reuses circuits for multiple TCP connections, it is possible to associate non anonymous and anonymous traffic at a given exit node, so be careful about what applications you run concurrently over Tor. Perhaps even run separate Tor clients for these applications. Read these papers especially the ones in boxes to get up to speed on anonymous communication systems.
Requiring every Tor user to be a relay would help with scaling the network to handle all our users, and running a Tor relay may help your anonymity. Providing service to these clients is a critical part of providing effective anonymity for everyone, since many Tor users are subject to these or similar constraints and including these clients increases the size of the anonymity set.
That said, we do want to encourage Tor users to run relays, so what we really want to do is simplify the process of setting up and maintaining a relay. First, we need to make Tor stable as a relay on all common operating systems. See Section 4.
Second, we still need to get better at automatically estimating the right amount of bandwidth to allow. Third, we need to work on scalability, both of the network how to stop requiring that all Tor relays be able to connect to all Tor relays and of the directory how to stop requiring that all Tor users know about all Tor relays. Changes like this can have large impact on potential and actual anonymity. Again, UDP transport would help here.
Three different research papers describe ways to identify the relays in a circuit by running traffic through candidate relays and looking for dips in the traffic while the circuit is active. These clogging attacks are not that scary in the Tor context so long as relays are never clients too. This would be handy, because it would make Tor better able to handle new protocols like VoIP, it could solve the whole need to socksify applications, and it would solve the fact that exit relays need to allocate a lot of file descriptors to hold open all the exit connections.
Some of the hard problems are:. Right now the path length is hard-coded at 3 plus the number of nodes in your path that are sensitive. Remember that the best way to attack Tor is to attack the endpoints and ignore the middle of the path. Currently there is no reason to suspect that investigating a single relay will yield user-destination pairs, but if many people are using only a single hop, we make it more likely that attackers will seize or break into relays in hopes of tracing users.
Now, there is a good argument for making the number of hops in a path unpredictable. Choosing path length from, say, a geometric distribution will turn this into a statistical attack, which seems to be an improvement. On the other hand, a longer path length is bad for usability, and without further protections it seems likely that an adversary can estimate your path length anyway.
Please write a research paper that tells us what to do. It is better to not manually change the path. There are many attacks and adversaries that Tor is trying to defend against at once, and constraining paths has surprising trickle-down effects on the other attacks e. Picking your entry and exit in different countries is not a good defence, because it only defends against adversaries that are unable to rent servers in other countries. This approach is more well-understood in the context of high-latency systems.
See e. This would be great for two reasons. Second, it is conceivable that we could get increased security against certain attacks by migrating streams periodically, since leaving a stream on a given circuit for many hours might make it more vulnerable to certain adversaries. There are two problems though. First, Tor would need a much more bulky protocol.
Right now each end of the Tor circuit just sends the cells, and lets TCP provide the in-order guaranteed delivery. If we can move streams across circuits, though, we would need to add queues at each end of the circuit, add sequence numbers so we can send and receive acknowledgements for cells, and so forth. These changes would increase the complexity of the Tor protocol considerably. Circuits are typically three hops long, so in about a third of the cases we just lose.
But there are still some approaches we can take to improve the reliability of streams. The main approach we have now is to specify that streams using certain application ports prefer circuits to be made up of stable nodes. These ports are specified in the "LongLivedPorts" torrc option, and they default to.
The definition of "stable" is an open research question, since we can only guess future stability based on past performance. Right now we judge that a node is stable if it advertises that it has been up for more than a day. Down the road we plan to refine this so it takes into account the average stability of the other nodes in the Tor network.
You cannot trust the network to pick the path for relays could collude and route you through their colluding friends. This would give an adversary the ability to watch all of your traffic end to end. The default exit policy blocks certain private net blocks, like Some overzealous firewall configs suggest that you also block all the parts of the Internet that IANA has not currently allocated.
Second, why should we default-reject something that might one day be useful? It would be nice to let relay operators say things like "reject www. There are two problems, though. First, users could still get around these blocks. For example, they could request the IP address rather than the hostname when they exit from the Tor network. This means operators would still need to learn all the IP addresses for the destinations in question. The second problem is that it would allow remote attackers to censor arbitrary sites.
For example, if a Tor operator blocks www1. Tor only transports data, it does not inspect the contents of the connections which are sent over it. Further, and more importantly, which definition of "certain content" could we use? Every choice would lead to a quagmire of conflicting personal morals. The only solution is to have no opinion. Like all anonymous communication networks that are fast enough for web browsing, Tor is vulnerable to statistical "traffic confirmation" attacks, where the adversary watches traffic at both ends of a circuit and confirms their guess that those endpoints are communicating.
It would be really nice if we could use cover traffic to confuse this attack. But there are three problems here:. We hope that one day somebody will prove us wrong, but we are not optimistic. We did however since implement netflow padding to collapse netflow records for improved security. This has the goal of stymying some of the potential traffic analysis attacks out there -- website fingerprinting, end-to-end correlation, and the things in between.
For details see the blog post by the Tor network team, the announcement on the tor-dev mailinglist or read further publications on padding. Many people suggest that we should use steganography to make it hard to notice Tor connections on the Internet. There are a few problems with this idea though:.

You should let people choose their path length. You should change path selection to avoid entering and exiting from the same country. You should split each connection over many paths.
You should migrate application streams across circuits. You should let the network pick the path, not the client. Your default exit policy should block unallocated net blocks too. Exit policies should be able to block websites, not just IP addresses. You should change Tor to prevent users from posting certain content.
You should use steganography to hide Tor traffic. General: What is Tor? The name "Tor" can refer to several different components. There are many reasons why the Tor network is currently slow. What can you do to help? Help make the Tor network large enough that we can handle all the users who want privacy and security on the Internet. Help us make Tor more usable. We especially need people to help make it easier to configure your Tor as a relay.
Also, we need help with clear simple documentation to walk people through setting it up. There are some bottlenecks in the current Tor network. Help us design experiments to track down and demonstrate where the problems are, and then we can focus better on fixing them. Tor needs some architectural changes too. One important change is to start providing better service to people who relay traffic. Help do other things so we can do the hard stuff. Help find sponsors for Tor. Do you work at a company or government agency that uses Tor or has a use for Internet privacy, e.
If your organization has an interest in keeping the Tor network working, please contact them about supporting Tor. Without sponsors, Tor is going to become even slower. It adds up! User support: With this many users, a lot of people are asking questions all the time, offering to help out with things, and so on.
We need good clean docs, and we need to spend some effort coordinating volunteers. Relay support: the Tor network is run by volunteers, but they still need attention with prompt bug fixes, explanations when things go wrong, reminders to upgrade, and so on. The network itself is a commons, and somebody needs to spend some energy making sure the relay operators stay happy. We also need to work on stability on some platforms — e.
Usability: Beyond documentation, we also need to work on usability of the software itself. This includes installers, clean GUIs, easy configuration to interface with other applications, and generally automating all of the difficult and confusing steps inside Tor.
Usability for privacy software has never been easy. Incentives: We need to work on ways to encourage people to configure their Tors as relays and exit nodes rather than just clients. Естественно, бывают случаи, когда браузер очень долго загружает странички. Традиционно странички загружаются долго, поэтому что их прокси-сервер очень удален, что приводит к высочайшему пингу и низкой пропускной возможности. Для роста скорости веба его нужно заменить либо на сто процентов отключить, в зависимости от ситуации.
Заходим в програмку. Нажмите клавишу в виде 3-х полосок в правом верхнем углу. А позже зайдите в «Настройки». Бывает, что браузер включает в себя все функции веб-сайтов и по данной для нас причине скорость загрузки понижается. Чтоб выбрать лучший уровень сохранности, необходимо выполнить несколько обычных шагов:.
В сети нередко появляются вопросцы о том, как убыстрить работу браузера Tor. Но следует осознавать, что этот интернет-браузер работает медлительно из-за того, что пользовательский трафик многократно шифруется для заслуги анонимности. По данной для нас причине интернет-страницы не могут загружаться быстро.
Основное преимущество Tor Browser заключается в том, что он очень прячет положение юзера и остальные данные при просмотре Веба. Это достигается с помощью так именуемой луковой маршрутизации, когда к входящему сетевому трафику применяется множественное шифрование и он сам проходит через группу промежных узлов, и это происходит много раз.
Но у таковой степени защиты есть несколько существенных недочетов. Более приметным из их является медленная загрузка веб-страниц, которая не таковая стремительная, как в остальных браузерах. Но следует осознавать, что это не какая-то неувязка, которую необходимо решать и решать. Это совсем не неувязка, а особенная функция, и для вас необходимо с ней разобраться. Сейчас вы осознаете, почему Tor работает так медленно: это соединено с многократным шифрованием входящего и исходящего сетевого трафика, без которого нереально достигнуть анонимности юзера в сети.
Но возможны и ситуации, когда интернет-браузер очень долго «думает» отлично, а, к примеру, ранее так было не так. В таковых вариантах стоит уточнить некие нюансы:. Для подключения к Вебу юзер может активировать прокси-сервер. А ежели он чрезвычайно удален, имеет высочайший пинг и низкую пропускную способность, интернет-страницы будут загружаться еще медлительнее, чем традиционно. Итак, чтоб прирастить скорость веба в браузере Tor, для вас следует его поменять либо на сто процентов отключить.
Давайте узнаем, как это сделать:. Когда странички открываются долго, возникает вопросец, как убыстрить Yandex Браузер. Для этого существует целый комплекс мероприятий по чистке и оптимизации. В конце концов, стоит держать в голове, что оборудование играет важную роль в функционировании компа и, в частности, браузера. ПО на данный момент довольно ресурсоемкое и старенькый ПК при всем желании и наибольшей оптимизации не справляется с перегрузкой.
Тут стоит пошевелить мозгами о переходе на наиболее массивное оборудование. Аннотация по ускорению работы Yandex. Браузера на слабеньких компах, на которых по определенным причинам не удается обновить составляющие. Следуйте описанным шагам, чтоб получить итог. Мы решим все эти задачи, чтоб убыстрить работу компа в Вебе, без конструктивного обновления компонентов. Все, что для вас необходимо сделать, это следовать приведенным ниже инструкциям.
Подробная аннотация по ускорению работы веб-сайта. Как проверить скорость загрузки веб-сайта, какова обычная скорость загрузки веб-сайта, от чего же она зависит и как без помощи других сделать лучше скорость загрузки веб-сайта. Неоптимизированные изображения — самая «сложная» часть веб-сайта.
Потому работа с изображениями может существенно прирастить скорость. Ежели вы запечатлели продукт и получили фото шириной около пикселей, сможете смело уменьшать ширину до , в большинстве случаев этого будет довольно. Исключением будут те веб-сайты в основном интернет-магазины , где можно просмотреть продукт с «лупой», но даже там увеличенное изображение загружается не сходу, а лишь в том случае, ежели человек решит пользоваться сиим инвентарем.
Перед размещением на веб-сайте изображения с камеры можно и необходимо сжимать по размеру. Они делают это в Photoshop либо другом редакторе изображений либо через онлайн-сервисы, такие как TinyPNG либо Optimizilla. Ежели у вас есть фото товаров либо выполненная работа и есть страничка с их перечнем, было бы уместно сделать маленькие превью эскизы.
Тогда перечень продуктов, работ либо фото загрузится скорее. Представьте для себя, сколько времени потребовалось бы для загрузки перечня продуктов, ежели бы Спортмастер употреблял лишь уникальные изображения наиболее кб. Когда вы проверите скорость работы веб-сайта через Google PageSpeed, вы получите готовый перечень изображений, которые следует оптимизировать:.
Gzip — это программа для сжатия файлов на сервере аналог zip-архивов на компе. Ежели Gzip включен, сервер заархивирует эти файлы перед отправкой кода странички а также скриптов, стилей и иной текстовой инфы в браузер.
Браузер получит архив и распакует его на компе юзера. Сжатая информация будет скорее передаваться меж браузером и сервером. Ежели у вас не Apache, а Nginx кто знает, усвоит , то для вас пригодится файл конфигурации nginx. Добавьте код в раздел http и перезапустите сервер:. Ежели у вас нет доступа к htaccess либо конфигурации сервера, напишите в службу поддержки хостинга, для вас нужно включить сжатие gzip.
Когда браузер загружает веб-сайт, он сохраняет часть инфы с него файлы стилей, скрипты, изображения в собственной памяти кеш, кеш. Потом, на остальных страничках этого веб-сайта либо когда вы вернетесь на текущую страничку, браузер больше не будет запрашивать эту информацию с сервера что долго , а будет загружать ее из собственной памяти что скорее.
Чтоб употреблять кеш браузера, для вас нужно указать ему, какие типы файлов с вашего веб-сайта необходимо кэшировать. Как это сделать:. Ежели у вас нет доступа к настройкам сервера, напишите в техподдержку еще раз и попросите настроить кеширование статических файлов. Обратите внимание, что вы сможете настроить кеширование лишь для собственных ресурсов. Вы не можете поменять опции кеширования, к примеру, для скриптов Yandex. Минификация — это уменьшение размера файла за счет удаления пробелов, пустых строк, комментариев, использования наиболее маленьких имен переменных и т.
Браузеру все равно, с каким файлом работать — обыденным либо свернутым, да и весит таковой файл меньше. Популярные плагины и библиотеки jQuery, Bootstrap и т. Вы чувствуете разницу? Единственный недочет минификации — утрата читабельности файла. Ежели необходимо внести конфигурации в сжатый файл, сделать это будет трудно, человеку неловко работать с таковым файлом там сплошная линия.
Потому для минимизации ваших скриптов традиционно употребляются доп плагины CMS — они автоматом сжимают файлы css и js перед их загрузкой на веб-сайт. В то же время верстальщик может просто работать с обыкновенными версиями файлов.
