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.
