Startup Linux Processes

[Asphexis]

When I run ps -e, I see a lot of processes that I have no clue what they do. I only run one server off this machine, so is it possible to cut down on all of these processes? Are they system critical? They seem to start everytime the VDS starts, so I don't know.

Many of those are kernel worker threads that should be left on. Others are system-critical daemons. The only ones here that I think you could consider turning off would be the irqbalance service and cpuset.

Thanks for your response. I appreciate it.
