My biggest concern is not CPU load, as it tend to tell you nothing, e.g.
what is the implication of decreasing CPU from 70% to 60%?

I am more interested in real figures, e.g.  length of queue of pending
connections decrease from 10 to 5, average request time decrease from 100ms
to 50ms for example..

Thanks anyway.
