Subject: Re: [PATCH 2/2] sched/fair: Adjust the allowed NUMA imbalance when SD_NUMA spans multiple LLCs

Message-ID: <CAE4VaGDZ1Tf5UuDz+nB5OhAD70395-sXZgMNa2G69BJs2fafEg@mail.gmail.com> (raw)

Hi Mel,
we have tested 5.17.0_rc2 + v6 of your patch series and the results
are very good!
We see performance gains up to 25% for the hackbench (32 processes).
Even more importantly, we don't see any performance losses that we
have experienced with the previous versions of the patch series for
NAS and SPECjbb2005 workloads.
Tested-by: Jirka Hladky <jhladky@redhat.com>
Thanks a lot
Jirka
