Tx, but now after reading this article http://wiki.archlinux.org/index.php/Cpufrequtils I first went another way and manipulated ondemand threshold, I edited /etc/rc.local as follows:
#!/bin/sh -e # # rc.local # # This script is executed at the end of each multiuser runlevel. # Make sure that the script will "exit 0" on success or any other # value on error. # # In order to enable or disable this script just change the execution # bits. # # By default this script does nothing. echo 20 > /sys/devices/system/cpu/cpu0/cpufreq/ondemand/up_threshold exit 0 cpu1 is linked to cpu0 on my amd system, if it were not I might have to add a second line for cpu1. By default 'cat /sys/devices/system/cpu/cpu0/cpufreq/ondemand/up_threshold' showed 80 when running 2.6.31-9-rt. In 2.6.31-15-generic it's 95. Setting up_threshold as recommended in these articles to 50 or 35 did not do the job, had to lower it to 20. Now qjackctl shows the same cpu-load and few xruns as when I set cpufreq from ondemand to highest value. Next I will do is testing this on my Notebook with intel dualcore.
