I am very new to Litespeed but I must say I have been hugely impressed by it's performance. We went from a dedicated server with server loads around 1 to a vps hybrid and using Litespeed and server loads barely go over .30. I am trying to use some sort of cache and have found a lot of conflicting information in what can or can't be used. I would like to use APC or xcache. I have them both installed and they both work to an extent. Both seem to reset after so many seconds or minutes almost like the web server is restarted. I am only trying one at a time, as I know you can't have two opcode caches running at the same time. I also have php suexec enabled for users home directory in the configuration for litespeed. It is a CentOS server using Cpanel. Any help would be appreciated.
