Hello,
kernel test robot noticed a 23.4% improvement of stress-ng.pthread.ops_per_sec on:
commit: 7903f907a226058ed99f86e9924e082aea57fc45 ("pid: perform free_pid() calls outside of tasklist_lock")
https://git.kernel.org/cgit/linux/kernel/git/next/linux-next.git master
testcase: stress-ng
config: x86_64-rhel-9.4
compiler: gcc-12
test machine: 224 threads 2 sockets Intel(R) Xeon(R) Platinum 8480CTDX (Sapphire Rapids) with 256G memory
parameters:
nr_threads: 100%
testtime: 60s
test: pthread
cpufreq_governor: performance
In addition to that, the commit also has significant impact on the following tests:
