rc.conf:

MODULES=(acpi-cpufreq cpufreq_ondemand cpufreq_powersave)
DAEMONS=(!hwclock syslog-ng @network @netfs @crond @dbus gdm @cpufreq @acpid laptop-mode @sensors @microcode)

its strange that the cpu has only 800MHz during the bench.
my ondemand threshold: 95
does the bench cause less then 95%?

Maybe I am being a bit thick this morning, but what is your point?

Re: [S]bad perf b/c (lack of fine-tuning)/(wrong governor)/(redundancy)?

does the bench cause less then 95% load?
should the threshold be lower?
do you really need laptopmodetools, acpi, cpufreq & acpid? or could i deinst one of them?
should i use another cpu-gov?

Re: [S]bad perf b/c (lack of fine-tuning)/(wrong governor)/(redundancy)?

While I ran the benchmarks gkrellm showed my cores running at 3200MHz,
yet the hardinfo results never reported higher than 2500MHz.

This on a 3x AMD AthlonII X3 450, modules powernow_k8 and cpufreq_ondemand.
Stepping is 800-2000-2500-3200. Threshold is the default 95%.

I don't think hardinfo is reporting cpu frequency correctly.

Aha. Check out this bug from the hardinfo site:
http://bugs.hardinfo.org/showreport.php?bugid=48

This is a known bug. If you're using cpufreq with the ondemand governor, then the tests will be performed at 3GHz on your machine, as they're quite CPU intensive and the governor will automatically pump out more juice to the CPU.

However, HardInfo only measures the CPU speed once, and that's the speed it displays on the benchmark window.

Oh thank you for the answer, good Sir!
Can you answer the 3rd question?: do you really need laptopmodetools, acpi, cpufreq & acpid? or could i deinst one of them?

Re: [S]bad perf b/c (lack of fine-tuning)/(wrong governor)/(redundancy)?

If you are using laptopmodetools to govern the cpu scaling then you don't need the cpufreq dameon, the acpid daemon is used to send events to laptopmodetools.
