WordPress Benchmark

We compared the speed at which different web servers and caching platforms respond to requests for WordPress pages on a cPanel setup, using both non-keep-alive and keep-alive connections.

Our test platforms included:

  • LiteSpeed Enterprise (LSWS) using the popular W3 Total Cache and WPRocket WordPress cache plugins, as well as with our LiteSpeed Cache Plugin for WordPress.
  • Apache using the W3 Total Cache and WPRocket WordPress cache plugins.

Our results showed Apache (with keep-alive enabled) peaking around 1,300 and 700 requests per second with W3TC and WPRocket, respectively.

With the exact same setup, LSWS with W3TC and WPRocket delivered around 4,800 requests per second, an improvement factor of over 2.6x or 6x respectively.

Using the LiteSpeed Cache Plugin for WordPress with LSWS easily handled close to 5,200 requests per second.
