If you are trying to reduce power consumption, why are you limiting Cx
states to C2 (which save little) and not C3 (which will save a LOT of
power when the CPU is not heavily loaded).
With my hardware, i5-650, using C3 does not result in lower power consumption
versus C2. Both states draw

On my previous post I forgot to set kern.hz=100. This change does lower idle
power from 71w to 62w.

I guess that the credit for power saving goes mostly to the CPU
architects. Powerd only gives second-order savings, and C1 vs. C3
is ineffective, at least for HZ=1000

it isn't such a big deal in my opinion. The %efficiency at low
levels is misleading if you don't factor out the 5-10W plateau for
keeping the
PSU alive (fan, ballast, etc.). See for instance
My point is: if you
