I just thought of another way to improve the ondemand driver slightly. There is a file called up_threshold in the /sys/devices/system/cpu/cpu0/cpufreq/ondemand/ directory. This file defaults to 80 meaning that the cpu use was 80% over the last time period. This is high enough that it will usually require more than one time period to reach this. If you set it to something like 40% then it will often reach it in less than one time period.
Thanx. Will try that out.
I am assuming that you have already set the sampling_rate to sampling_rate_min.
You're assuming right.
You should only need to set these at boot, so they could go in /etc/rc.local or /etc/sysfs.conf (sysfsutils package).
Will have to see into that. On my machine, the entire .../ondemand directory with all of its contents vanishes as soon as the governor gets changed from "ondemand" to anything else.
