Some machines will run at high load averages, without any performance problems. But generally, a Web server should be under 1 unless it's doing something special like a backup.
Try running top, and look at the %CPU in the list of processes. That'll tell you if something specific is using lots of CPU time.
CPU is not everything - if IO is the limit (hard drives, network) then site will still appear to be slow, while CPU usage will be low as it will be waiting for data to come back. Unix commands given above should show IO load as well as CPU tho.
