Subject: [linus:master] [mm] c544a952ba: vm-scalability.throughput 33.3%
improvement
Hello,
kernel test robot noticed a 33.3% improvement of vm-scalability.throughput on:
commit: c544a952ba61b1a025455098033c17e0573ab085 ("mm: pcp: increase pcp->free_count threshold to trigger free_high")
https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git master
testcase: vm-scalability
config: x86_64-rhel-9.4
compiler: gcc-12
test machine: 128 threads 2 sockets Intel(R) Xeon(R) Platinum 8358 CPU @ 2.60GHz (Ice Lake) with 128G memory
parameters:
runtime: 300s
test: lru-file-mmap-read
cpufreq_governor: performance
In addition to that, the commit also has significant impact on the following tests:
+------------------+---------------------------------------------------------------------------------------------+
| testcase: change | stress-ng: stress-ng.mlockmany.ops_per_sec 26.2% improvement |
| test machine | 192 threads 2 sockets Intel(R) Xeon(R) 6740E CPU @ 2.4GHz (Sierra Forest) with 256G memory |
| test parameters | cpufreq_governor=performance |
| | nr_threads=100% |
| | test=mlockmany |
| | testtime=60s |
