Subject: [workqueue/tracing] 83b62687a0: aim9.signal_test.ops_per_sec -6.1%
regression
Greeting,
FYI, we noticed a -6.1% regression of aim9.signal_test.ops_per_sec due to commit:
commit: 83b62687a05205847d627f29126a8fee3c644335 ("workqueue/tracing: Copy workqueue name to buffer in trace event")
https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git master
in testcase: aim9
on test machine: 256 threads Intel(R) Genuine Intel(R) CPU 0000 @ 1.30GHz with 112G memory
with following parameters:
testtime: 5s
test: all
cpufreq_governor: performance
ucode: 0xffff0190
test-description: Suite IX is the "AIM Independent Resource Benchmark:" the famous synthetic benchmark.
test-url: https://sourceforge.net/projects/aimbench/files/aim-suite9/
