In that case you have too much hardware. Why would only using 2% be ideal? I would say 30-50% for normal usage and allowing for spikes. Servers can run at above 100% usage too don't forget..it just gets slower. A load of 1 = 100% for 1 cpu. So a quad at 2.0 load is using 50% of resources. At least that's how it's suppose to work. Litespeed is fast and if your load is now 11% then even better and congrats.
