SubjectRe: [RFC PATCH v2] sched: Limit idle_balance()
Hi Json,

I ran ebizzy and kernbench benchmarks on your 3.11-rc1 + your "V1
patch" on a 1 socket, 16 core powerpc machine. I thought I would let you
know the results before I try your V2.

Ebizzy: 30 seconds run. The table below shows the improvement in the
number of records completed. I have not spent enough time on the patch
to explain such a big improvement.

Number_of_threads %improvement_with_patch
4 41.86%
8 9.8%
12 34.77%
16 28.37%

While on kernbench there was no significant change in the observation.

I will try patch V2 and let you know the results.

Regards
Preeti U Murthy
