Subject: [clocksource] 8901ecc231: stress-ng.lockbus.ops_per_sec -9.5%
regression
Greeting,
FYI, we noticed a -9.5% regression of stress-ng.lockbus.ops_per_sec due to commit:
commit: 8901ecc2315b850f35a7b8c1b73b12388b72aa78 ("clocksource: Retry clock read if long delays detected")
https://git.kernel.org/cgit/linux/kernel/git/next/linux-next.git master
in testcase: stress-ng
on test machine: 96 threads 2 sockets Intel(R) Xeon(R) Gold 6252 CPU @ 2.10GHz with 192G memory
with following parameters:
nr_threads: 100%
disk: 1HDD
testtime: 60s
class: memory
test: lockbus
cpufreq_governor: performance
ucode: 0x5003006
please be noted below in dmesg.xz (attached)
