To install the module, you need a server with CentOs or CloudLinux 6, 7 or 8 and a valid cPanel installation.

The module can be installed with a single shell command line. You’ll need to connect in the server’s root access and run the following command to start the installation script. (more details about the installation can be found)

Once the installation process is done, your 60-day free trial will start immediately.

Like every caching system, the possibility of emptying the cache is a must. Ideally if a site could control the cache purging itself, this would make things even simpler. With this in mind, we’ve developed a plugin for WordPress that automatically clears the cache of a site when a page is modified. We have also created a PHP class which can be integrated into any sites.

WordPress Plugin

The “Cache purge for Website Accelerator” plugin will purge the server cache memory every time a page or article is modified, to prevent old pages from being displayed.

PHP Class

We’ve placed an open source PHP class on GitHub allowing any developer to quickly include the server cache purging method into their code.

Incredibly Fast! Need proof?

When something seems too good to be true, it often is. Therefore, we’ve made two identical WordPress sites so you can compare them.

A benchmark test ran with the “Siege” software showed that simply placing Nginx in front of cPanel Apache increase the number of pages the site could serve by 137% (this test was made on a WordPress site with approximately 25 plugins installed).

Now, add website caching directly in Nginx. Each site can then be tweaked for optimal caching. With previous experiences acquired through other caching systems like Varnish, we transposed our knowledge into easy-to-use options directly in cPanel. While simply activating the cache in cPanel accounts of a server, we’ve managed to increase performance by 204% on the amount of requests the site could serve.

We’ve placed two copies of the same WordPress site online. One with the Nginx cPanel (WSA) module activated and one without, so you can compare with a live scenarios.
