This might not really indicate any problem. Firstly, what are your # sysctl dev.cpu.0.freq_levels Try watching the current cpu speed (dev.cpu.0.freq) while running under powerd. You can watch it shift under various loads by running 'powerd -v' in foreground, show it by running a script sleeping for eg a minute, or use (say) gkrellm with gkfreq plugin to display cpu speed constantly. Point being, if powerd has selected your lowest cpu frequency because load is less than default (or as specified by -i and -r switches) and this is (say) 1/4 of full speed, then something that normally showed 5% cpu will now show as using 20% (of available cpu cycles at that speed) You can tune your powerd idle levels more towards performance, and/or you can set a higher minimum cpu freq with sysctl debug.cpufreq.lowest from among your available levels. powerd's default shiftpoints work on my T23, but it's only a 2-speed :) Cheers, Ian _______________________________________________ email@example.com mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"
