minimum services list in runlevel 3

[Wolle]

Hi guys, I host a server which runs in runlevel 3 and is mainly there to host a game server.
The hole server lags from time to time and I was wondering if I could turn off a few services that are currently running in init 3. This is the list of services that are running atm.

Thanks Seve, the 2nd link is really useful.
After a clean reboot I now have these services running.
Do you see a service that doesn't need to run? Im not sure about hald.

Hello:
You need haldameon, other than that is looks like you have pared it down a lot. You may also want to have a look at the jobs / schedulers that run from cron. If this kicks in when your server is very busy it may / will cause some performance lag.
