Subject: Re: CFS Bandwidth Control - Test results of cgroups tasks pinned vs unpinned
Hi Kamalesh,
I'm unable to reproduce the results you describe. One possibility is
load-balancer interaction -- can you describe the topology of the
platform you are running this on?
On both a straight NUMA topology and a hyper-threaded platform I
observe a ~4% delta between the pinned and un-pinned cases.
Thanks -- results below,
- Paul
