This for confirming my observation. It seems much better than the 50% regression
reported earlier (with 2.6.26-rc1 and CONFIG_USER_SCHED).

Ideally we should get same results with CONFIG_USER_SCHED also (in
2.6.26-rc1). That needs some work in load balance code. Till that is
tackled, IMHO we can retain all the current code by either:

1. Disabling CONFIG_GROUP_SCHED (or better)
2. Enable CONFIG_GROUP_SCHED and CONFIG_CGROUP_SCHED

Ingo/Peter, What's your opinion?
