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.
