Perhaps I should have said that differently: it is being throttled by powerd. It doesn't have to do the measuring of the average itself. > >I was thinking there might be a counter/timer which is linked to the cpu > >clock, but sofar I haven't been able to find one. > > Well, you can see the current CPU frequency by looking at dev.cpu.0.freq > where 0 is the id of the CPU you want to query. At the times I take measurements the cpu tends to run at 100%, which would result in a nice flat line. -- greetz Joost [EMAIL PROTECTED] _______________________________________________ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"
