Rafael, we can close this bug i think. The group scheduler related
interactivity problems in early .25-rc were resolved via:
| commit 62fb185130e4d420f71a30ff59d8b16b74ef5d2b
| Author: Peter Zijlstra <a.p.zijlstra@chello.nl>
| Date: Mon Feb 25 17:34:02 2008 +0100
|
| sched: revert load_balance_monitor() changes
[...]
| Namely:
| - very frequent wakeups on SMP, reported by PowerTop users.
| - cacheline trashing on (large) SMP
| - some latencies larger than 500ms
that includes Xorg's fragility to certain types of delays. It should be
resolved by now and i havent seen it resurface.
we are now back to the 2.6.24 state of things. Which isnt as perfectly
interactive as the non-group-scheduler 2.6.24, but which is still more
interactive than say 2.6.22.
Peter is working on improving it even more, but that's 2.6.26 material.
Ingo
