Thank you Ray Lee and Mike Galbraith for your responses, I ran the
script and attached its gathered information.

I could reproduce "hard" load by just compiling the linux kernel, make
-j3 while reading mails with Thunderbird, which is not that hard
foreground load. Thunderbird starts reacting really slowly while compiling.

My system has a 1,3 GHz AMD Athlon CPU (32 bits) and 1 GB of RAM. Now
you will say: That is not very much. Of course it is not, but with the
old scheduler, the system felt way faster, so it seemed to be enough for
compiling and reading mails.
I hope you can find useful information in the attached log, I enabled
SCHED_DEBUG and SCHEDSTATS, if you need any more information, just ask
me, I will try to answer.

And thank you all for your help,

Nico Schümann
