Comment 16 for bug 107545

@Owen and @draft:
If you can reproduce the bad performance of flash videos, please try if lowering the sampling_rate would help. Minimum is 10000 us, try 40000 us (= 25 fps):

$ sudo su
$ echo 40000 >/sys/devices/system/cpu/cpu0/cpufreq/ondemand/sampling_rate

If the peaks of CPU demand are too fast while rendering flash videos we should consider lowering the sampling_rate and not up_threshold. The sampling overhead seems pretty low meanwhile and a reasonable up_threshold can save much power.
