High CPU Usage

If you are experiencing high CPU usage on your site, there are three possible ways WP Rocket could cause this:


Our cache preload bot

Some servers do not like our preload bot. You can ask us to turn this off and see if that helps. See this article:
Disable Preload Bot


Your pages are not being cached

Make sure that WP Rocket is active and caches your pages:

Occasionally minification can cause high CPU usage in cases where your site has a lot of CSS or JS files. Try disabling the minification options and then monitor your CPU usage to see if it helps.
