Subject: [linus:master] [sched/fair] 74eec63661:
stress-ng.resched.ops_per_sec 21.9% improvement
Hello,
kernel test robot noticed a 21.9% improvement of stress-ng.resched.ops_per_sec on:
commit: 74eec63661d46a7153d04c2e0249eeb76cc76d44 ("sched/fair: Fix NO_RUN_TO_PARITY case")
https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git master
testcase: stress-ng
config: x86_64-rhel-9.4
compiler: gcc-12
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
test: resched
cpufreq_governor: performance
In addition to that, the commit also has significant impact on the following tests:
+------------------+----------------------------------------------------------------------------------------------+
| testcase: change | stress-ng: stress-ng.resched.ops_per_sec 19.4% improvement |
| test machine | 256 threads 2 sockets Intel(R) Xeon(R) 6767P CPU @ 2.4GHz (Granite Rapids) with 256G memory |
| test parameters | cpufreq_governor=performance |
| | nr_threads=100% |
| | test=resched |
| | testtime=60s |
