You'd need to provide more detail - specifically what processes are running

 

by: CemPosted on 2009-11-06 at 20:11:36ID: 25764955

GameServers like Half Life counter strike, GTA SA, etc. MySQL aswell.

Please post the output from something like top when the problem occurs.  There is no point in guessing what's causing the high load.

I suggest you install and run "htop".
It is a very nice alternative to "top" and it manages quite better threads, cores and cached RAM. It is fully configurable with keyboard shortcuts and mouse.

To see exactly what's taking you most CPU run it then type F2 (Setup), under Display options select both Hide userland threads and Highlight program "basename", type F10 (Done).
You can also see which processes are using most RAM (or other resources) with F6.
