Hi Ingo & everbody on the list,
first of all: many thanks for developing this great scheduler (also:
kudos to Con Kolivas for having developed SD & CK-patchset)
(this is my second mail to this list and I hope I'm doing everything right)
I'm doing some backup during work right now: rsyncing my home
partition (nearly 180 GB) to another harddrive locally &
since I'm running compiz-fusion, openoffice and gnome, therefore am in
some real "working environment" I thought:
give Ingo's new scheduler a test-ride during heavy load ;)
first some impressions:
cpu load balancing looks great again (pretty symmetrical loading on
both cores - it looks pretty similar to 19.1 if not better if I recall
right),
v20 wasn't that "good-looking" ;) (with gnome-system-monitor)
both cpus have a continous load of ~ 70% right now so I'll be
starting up 9 instances of glxgears, below are some output & details
of my system
(cpu frequency switching is disabled since it doesn't work right now
with the current bios version)
short summary: unfortunately after starting glxgears everything
stuttered a lot, don't know if it's expactable during that heavy load
- just wanted to let you know; after having closed each instance of
glxgears, everything was fine again ...
cat /proc/sched_debug

Try setting features to 14. That helps my similar issues.
