 * Hi,
 * I have a server with 8CPUs and 16GB RAM and the plugin is causing lots of issues.
 * The latest updates seem to make the CPU to spike. When the Litespeed plugin is
   off, the CPU is about 0.27 however, when the plugin is on, the CPU goes to 1.60
   or higher at normal use, and sometimes it gets to 9 or more with red warning,
   so I had to restart the server.
 * Additionally, if you open a page, leave it open for 10 minutes or so, then re-
   load it, the CPU spikes and page takes a long time to load – sometimes I had 
   to restart the server because the plugin is using the full CPU resources. It 
   feels the plugin goes to deep sleep and when it wakes up, it struggles and brings
   the server down with it. This is just one page I am talking about.
 * I hope you can fix this issue and make sure that plugin is very light and not
   CPU intensive. WP Fastest Cache and WP Super Cache are very light on CPU and 
   had no issues.
 * Thanks
