Services to stop on CentOS

[iha81]

I currently have CentOS 4 on my dual xeon's and have about 89 total processes running. I want to disable all services/processes That I don't need in order to have my source servers running. This is the output of ps aux

I would like to disable ALL services i don't need. Any help would be appreciated

[cryotek]

The only services I can see you not needing is GPM which allows you mouse usage in console, cupsd which is the daemon for Common Unix Printer Service (CUPS), and MAYBE portmap, i knowI used to disable it. Other than that, everything else is pretty much standard, unless you buy another server for web/database and remove httpd and mysql from your Gameserver.

another command you can type is top. it shows you how many are actually active and which ones aint heres a example
