Subject: [linus:master] [mm, pcp] 362d37a106: netperf.Throughput_Mbps 14.5%
improvement
hi, Huang Ying,
when this commit is a review patch in
https://lore.kernel.org/all/20231016053002.756205-4-ying.huang@intel.com/
we made two reports
[1] 'a 14.6% improvement of netperf.Throughput_Mbps'
in https://lore.kernel.org/all/202310271441.71ce0a9-oliver.sang@intel.com/
now in mainline, we confirmed this commit cause similar performance change.
[2] 'a -60.4% regression of netperf.Throughput_Mbps'
in https://lore.kernel.org/all/202311061311.8d63998-oliver.sang@intel.com/
which per your education in
https://lore.kernel.org/all/87ttpzv11u.fsf@yhuang6-desk2.ccr.corp.intel.com/,
we know it's also an improvment in fact.
we also noticed similar results in mainline now, recorded in below
"In addition to that, the commit also has significant impact on the following tests:"
part.
just FYI about the results in maineline.
Hello,
kernel test robot noticed a 14.5% improvement of netperf.Throughput_Mbps on:
