Hello,
kernel test robot noticed a -50.6% regression of stress-ng.timer.ops_per_sec on:
commit: 71cc52f552ea8520d8bd7bec132853e9ff8dd6de ("posix-timers: Make signal delivery consistent")
https://git.kernel.org/cgit/linux/kernel/git/tglx/devel.git timers/posix
testcase: stress-ng
test machine: 224 threads 2 sockets Intel(R) Xeon(R) Platinum 8480CTDX (Sapphire Rapids) with 512G memory
parameters:
nr_threads: 100%
testtime: 60s
test: timer
cpufreq_governor: performance
In addition to that, the commit also has significant impact on the following tests:
+------------------+-------------------------------------------------------------------------------------------+
| testcase: change | stress-ng: stress-ng.timer.ops_per_sec -58.1% regression |
| test machine | 64 threads 2 sockets Intel(R) Xeon(R) Gold 6346 CPU @ 3.10GHz (Ice Lake) with 256G memory |
| test parameters | cpufreq_governor=performance |
| | nr_threads=100% |
| | test=timer |
| | testtime=60s |
+------------------+-------------------------------------------------------------------------------------------+
