right. Ok I'm running now 2.6.0 with Nick's v28p1: The results without
load and with kernel compile load are attached. On nice level 0 I get
now the stuttering sound which I described in the previous mail. When I
renice gnomemeeting to -10 it's actually usable but not as good as in
2.4.2x. It's still sensitive to window movement and X activity. Two
subjective observations are that the nice levels haven't got such a big
impact in Nick's scheduler they used to have and that the default
behaviour gnomemeetingwise is better than in earlier Nick schedulers.


No, nice levels don't have such a big impact. That is the last big
think I have to fix, but thats another story...

At nice -10, there is basically nothing more the scheduler can do
for it (nice -20 will be a tiny bit better again).

I'd say its due to either sound drivers or your app doing something
different when running in 2.6.



This might be a problem - try turning unmaskirq on, and possibly
32-bit IO support on (hdparm -u1 -c1 /dev/hda). I think there is
a remote possibility that doing this will corrupt your data just
to let you know.


Tried it and doesn't make a difference.


dang


So the 1 gnomemeeting process is doing everything? (except display of course)


AFAIK yes.
