Subject: Re: [PATCH -V3 3/9] mm, pcp: reduce lock contention for draining
high-order pages
hi, Huang Ying,
sorry for late of this report.
we reported
"a 14.6% improvement of netperf.Throughput_Mbps"
in
https://lore.kernel.org/all/202310271441.71ce0a9-oliver.sang@intel.com/
later, our auto-bisect tool captured a regression on a netperf test with
different configurations, however, unfortunately, regarded it as 'reported'
so we missed this report at the first time.
now send again FYI.
Hello,
kernel test robot noticed a -60.4% regression of netperf.Throughput_Mbps on:
