Subject: [linus:master] [mm] 728be28fae: stress-ng.rawsock.ops_per_sec 92.8% improvement
Date: Wed, 31 Jan 2024 15:20:54 +0800 [thread overview]
Message-ID: <202401311429.be2be5fc-oliver.sang@intel.com> (raw)
Hello,
kernel test robot noticed a 92.8% improvement of stress-ng.rawsock.ops_per_sec on:
commit: 728be28fae8c838d52c91dce4867133798146357 ("mm: migrate: remove THP mapcount check in numamigrate_isolate_page()")
https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git master
testcase: stress-ng
test machine: 64 threads 2 sockets Intel(R) Xeon(R) Gold 6346 CPU @ 3.10GHz (Ice Lake) with 256G memory
parameters:
nr_threads: 100%
testtime: 60s
class: network
test: rawsock
cpufreq_governor: performance
we doubt the performance improvement is caused by:
81.65 -6.0 75.61 mpstat.cpu.all.soft%
but we still cannot connect this with code change, so this report is just FYI
what we observed in our stress-ng tests.
Details are as below:
