Subject: Re: [patch 00/15] CFS Bandwidth Control V6

Hi,
I've run several tests including hackbench, unixbench, massive-intr
and kernel building. CPU is Intel(R) Xeon(R) CPU X3430 @ 2.40GHz,
4 cores, and 4G memory.
Most of the time the results differ few, but there are problems:
1. unixbench: execl throughout has about 5% drop.
2. unixbench: process creation has about 5% drop.
3. massive-intr: when running 200 processes for 5mins, the number
of loops each process runs differ more than before cfs-bandwidth-v6.
The results are attached.
