Varnish can vastly raise the performance of your websites. Find out how to make the most of its power.
Varnish is a web app accelerator, which has been gaining a lot in popularity lately, because it can increase the load speed of any website, sometimes even by one hundred percent, based on the content itself. This tool is occasionally referred to as an HTTP reverse proxy too and is used to decrease the overall load on the physical machine and to boost the browsing speed for the website visitors. Each time a visitor loads a page on a specific site, the browser request is processed by the web server and the requested information is returned as a response. If the Varnish accelerator is activated, it caches the pages that the visitor opens and in case any of them is opened again, it’s served by Varnish and not by the server directly. The improvement in the performance is due to the fact that the accelerator processes the browser requests considerably faster than any web server, which results in much faster browsing speeds for the visitors. In case any content is edited meanwhile, the cached webpages will also be updated the next time someone attempts to open them.
Varnish in Shared Hosting
You can take advantage of Varnish’s potential and optimize your websites’ load speed irrespective of the shared hosting plan that you’ve selected and you can enable and set up the platform with several mouse clicks from the easy-to-work-with interface offered by our avant-garde Hepsia hosting Control Panel. During the procedure, you will be able to choose two different things – how many sites will use the Varnish platform, in other words – the number of instances, and how much data will be cached, i.e. the amount of memory. The latter is available in increments of 32 megabytes and is not bound to the number of instances, so you can use more instances and less memory and vice versa. In case you have lots of content on a given website and you gain lots of website visitors, more memory will guarantee you better results. You may also consider employing a dedicated IP for the websites that will use the Varnish caching platform. The Hepsia Control Panel will provide you with easy 1-click buttons for turning off or restarting any instance, for deleting the cache associated with any site and for viewing comprehensive system logs.
