I have a web site (forum, friend network, etc) on my P4 3.0Ghz HT dedicated server. And CPU usage is almost 2.0 when 110users are online at the same time.

1. Is is normal?
2. If there is a problem, can it be script?
3. If there is a problemi can it be the server?

I need help!

Thank you

1. Seems a bit high
2. It could be scripting, especially poor SQL queries or DB design
3. It could be the server, especially RAM, although swap usually jumps the load quite a bit higher.

All in all, more information would help, but you may want to hire someone with experience in optimizing servers and code.

Depends.

If it becomes a serious performance issue, consider distributing the load with another system.

Try to run smth like `top` for some time and see what processes are eating most of the resources.
