Varnish
Learn about Varnish, learn more on web accelerators and see exactly what it is that they can do.
Varnish is a web application accelerator, which has been gaining a lot in popularity in recent years, because it can increase the speed of any website, sometimes even by 100%, depending on the content itself. This tool is sometimes referred to as a caching HTTP reverse proxy as well and is used to decrease the overall load on the physical machine and to accelerate the browsing speed for the website visitors. Each time a visitor loads a page on a certain website, the browser request is handled by the web server and the requested info is returned as a response. If the Varnish accelerator is enabled, it caches the web pages that the visitor browses and in case any of them is loaded once more, it is fetched by Varnish and not by the server directly. The performance boost comes from the fact that the accelerator processes the web requests considerably faster than any web server, which results in much faster browsing speeds for the visitors. In case any data is updated meanwhile, the cached pages will also be updated the next time somebody accesses them.

You can also see an elaborate log or clear the cache for any of the sites. When you add Varnish to your shared hosting plan, you’ll be able to choose the maximum amount of system memory that will be available to you for data caching purposes and how many websites will use Varnish. You can always add more memory in increments of 32 MB and, for optimum performance, you can set a dedicated IP address for the sites that will use Varnish. This will allow you to take full advantage of your Internet sites and to have a lot of satisfied users.

Varnish in Semi-dedicated Servers
The Varnish caching platform is included in the standard set of services that you’ll get when you decide to host your Internet sites in a
semi-dedicated server account. You can configure it for any of your Internet sites through our cutting-edge Hepsia hosting Control Panel. The default system memory that the Varnish caching platform can use to cache content is 64 MB, but in case you decide that you need more, you can upgrade this memory from the Control Panel’s Upgrades section. You can also upgrade the Varnish instances, i.e. the number of the sites that can use this platform simultaneously. As these two features aren’t tied to each other, you can use a couple of websites with the default memory or you can add more memory in increments of 32 megabytes and use all of it for one single web site. The Varnish platform performs best if you use a dedicated IP address for the Internet sites that utilize its power. Hepsia will give you an easy means of rebooting any instance. Furthermore, you’ll be able to delete the cached content with just a click.

Varnish in VPS Servers
The Varnish content caching platform is included by default with each of the
Linux VPS web hosting service that we offer given that the virtual machine is ordered with the Hepsia Control Panel, so you can improve the overall performance of your websites with just a few mouse clicks. The more powerful the package, the more system memory Varnish will have at its disposal, but even with a low-end plan, the platform will be able to utilize several hundred MB, so even if you manage a number of sites, you will notice a considerable decrease in the overall server load and a considerably better site loading speed. The Varnish platform will need to work for a little while while the visitors browse the site and once the site content has been cached, you’ll distinguish the effects. One of the benefits of using Varnish is that a less powerful and less pricey Virtual Private Server package will do the very same job as a more pricey one without the caching platform, so not only will your websites work considerably better, but you’ll also save a certain amount of money.

You can employ Varnish to optimize the load speed of any website that’s hosted on a
dedicated server with us when the Hepsia Control Panel is pre-installed on the machine. Not only will you get the content caching platform ready for use at no extra charge, but you’ll also exert complete control over it through Hepsia’s easy-to-navigate interface. It’ll take just one mouse click to start or shut down an instance or to clear the cached data associated with any site that’s using the Varnish platform and if you’re more tech-savvy, you can also check the platform’s logs. Varnish comes with no less than three gigabytes of memory for web content caching purposes, so even in case you run an immense number of websites on your dedicated server and they all use the Varnish platform, the difference in their performance will be detectable. You will just have to wait for a little while until Varnish caches whatever pages the visitors access on their end. The Varnish platform works best when the Internet sites use a dedicated IP address, but due to the fact that our dedicated servers include 3 charge-free IP addresses, you’ll have all that you need.
