Thanx for the suggestion, though. I'll keep trying.
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. I am assuming that you have already set the sampling_rate to sampling_rate_min. You should only need to set these at boot, so they could go in /etc/rc.local or /etc/sysfs.conf (sysfsutils package). -- Carl Johnson ca...@peak.org -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of "unsubscribe".
