CPU Time saved by WP-Super-Cache

I needed to make some changes to the website layout this afternoon, so I turned off WP-Super-Cache for a while. As you can clearly see in the following graph the CPU time consumed by php-cgi processes increased by 2-4 times when caching was turned off between 14:00-17:00. And this increase was caused by a single WordPress installation during low traffic hours.

This is one of the many reasons I love caching plugins.

    Wp-Super-Cache is indeed a great plugin. I decided to remove it from my wordpress blog and simple went with eaccelerator. My server loads sitting way down near 1… I do have a powerful xeon machine so that helps too :)
