Hi Billy,

That's actually a good point.

You want each "process" (in it's general definition) to be as efficient as possible and to use as little resources, including CPU as possible. Not so much because it'll waste resources (which may otherwise never be used so what are you really wasting) but simply because the task will take longer. However it you have a whole bunch of processes each wanting to use CPUs, well that's kinda why they're there and while nothing is unnecessarily waiting for the resource, which is the key point, you have an environment that can cope with the required demand.
