Subject: [linus:master] [posix] 513793bc6a: stress-ng.timer.ops_per_sec 69.3% regression
Date: Thu, 12 Dec 2024 21:47:11 +0800 [thread overview]
Message-ID: <202412122138.3f38f520-lkp@intel.com> (raw)
Hello,
kernel test robot noticed a 69.3% regression of stress-ng.timer.ops_per_sec on:
commit: 513793bc6ab331b947111e8efaf8fcef33fb83e5 ("posix-timers: Make signal delivery consistent")
https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git master
[test failed on linus/master fac04efc5c793dccbd07e2d59af9f90b7fc0dca4]
[test failed on linux-next/master d1486dca38afd08ca279ae94eb3a397f10737824]
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: timer
cpufreq_governor: performance
