Hi,

for some testing i installed X into a vserver.
It runs fine for small apps & games but when loading larger
programs or games, it seems to go very slow and a lot of
cpu cycles are wasted on idle time (>85%)
I have currently 8 vservers of which 1 template, 1 packet cache
and the rest of them don't take up a lot of cpu either.

This is what i tried to do to get more cpu cycles for that particular
vserver instance.

/etc/vserver/<vservername>
flags:
sched_prio
sched_hard

bcapabilities
CAP_SYS_RAWIO
SYS_NICE

nice
-20

schedule
30
2
1800
15
2000
dummy

I'm not sure i'm handling the schedule thing correctly as i'm not sure
that i understand it correctly. Judging from the fact that bigger apps
run waaaaaay slow (Athlon 1Ghz, 775 Mb RAM) i must be doing something wrong.
