Subject: [sched] d27e9ae2f2: aim9.sync_disk_rw.ops_per_sec -2.1% regression
Greeting,
FYI, we noticed a -2.1% regression of aim9.sync_disk_rw.ops_per_sec due to commit:
commit: d27e9ae2f244805bbdc730d85fba28685d2471e5 ("sched: Move /proc/sched_debug to debugfs")
https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git master
in testcase: aim9
on test machine: 256 threads 2 sockets Intel(R) Genuine Intel(R) CPU 0000 @ 1.30GHz with 112G memory
with following parameters:
testtime: 300s
test: sync_disk_rw
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/
In addition to that, the commit also has significant impact on the following tests:
+------------------+--------------------------------------------------------------------------------+
| testcase: change | stress-ng: boot-time.dhcp 7.3% regression |
| test machine | 96 threads 2 sockets Intel(R) Xeon(R) Gold 6252 CPU @ 2.10GHz with 512G memory |
| test parameters | class=filesystem |
| | cpufreq_governor=performance |
| | disk=1HDD |
| | fs=ext4 |
| | nr_threads=10% |
| | test=procfs |
| | testtime=60s |
| | ucode=0x5003006 |
