Hi Ingo,
I've been running the latest sched-git through some tests. Here is essentially what I am doing,
1. Mount the control group 2. Create 3-4 groups 3. Start kernbench inside each group 4. Run cpu hogs in each group
Essentially the idea is to see how the system responds under extreme CPU load.
This is what I get (and this is in a shell which belongs to the root group) [root@llm11 ~]# time sleep 1
real 0m1.212s user 0m0.004s sys 0m0.000s [root@llm11 ~]# time sleep 1
real 0m1.200s user 0m0.000s sys 0m0.004s [root@llm11 ~]# time sleep 1
real 0m1.266s user 0m0.000s sys 0m0.000s [root@llm11 ~]# time sleep 1
real 0m1.113s user 0m0.000s sys 0m0.000s [root@llm11 ~]#
On the sched-devel tree that I have, the same gives me following results.
[root@llm11 ~]# time sleep 1
real 0m1.057s user 0m0.000s sys 0m0.004s [root@llm11 ~]# time sleep 1
real 0m1.038s user 0m0.000s sys 0m0.004s [root@llm11 ~]# time sleep 1
real 0m1.075s user 0m0.000s sys 0m0.000s [root@llm11 ~]# time sleep 1
real 0m1.071s user 0m0.000s sys 0m0.000s [root@llm11 ~]# time sleep 1
real 0m1.073s user 0m0.000s sys 0m0.004s [root@llm11 ~]# time sleep 1
real 0m1.055s user 0m0.000s sys 0m0.004s
I agree this is not a very great test. Its getting a bit late here. I will get some better test case tomorrow morning (and if you have some, I can try those as well). I just did not want the tree to get merged in without further discussion.
