You can use apm. It will only save a few watts, but it may reduce the
cooling costs by reducing the heat generated by the CPU. If you have
_many_ machines you can easily reduce the temperature of the server room
by a few degrees C.

As far as I can see, any modern processor supports several states C0, C1, ...
Is there any way to take advantage of this into OpenBSD in order to reduce the
system consumption by falling the CPU in C1 state or higher ?

Note: When running with the lowest multiplier, HDD I/O performance may
suffer. In my case the lowest CPU rate is at 1000MHz and with full I/O
load accross 1 or 2 HDDs the CPU load is below the treshold of the apm

so it doesn't speed up. If I switch it manually with apm -H the
The disk I/O + samba doesn't stress the CPU enough so it does not speed up.
Which is good :) I expect my disk I/O to keep CPU usage low, that's why we
have all that DMA, I/O controllers and stuff.
Bad thing is, with the lowest CPU multiplier, something else is slowed
down. Maybe the
