I have systems running 7.4 and 8.2. The newer ones (in terms of age of
hardware) are always running at profhz, i.e., when executing a "systat
-vm 1" I see that all cores always get profhz interrupts per second.
An older machine running 7.4 is running at hz (which for this machine I
set to kern.hz=200 in loader.conf).
Using ps -o ...,flags,... I see that no process has profiling turned on.
Why is this so?
Especially on laptops, I'd like to save power by lowering the interrupt
rate.
Regards,
Martin
