Subject: [mm, slub] 3286222fc6: stress-ng.vfork.ops_per_sec 32.1%
improvement
Greeting,
FYI, we noticed a 32.1% improvement of stress-ng.vfork.ops_per_sec due to commit:
commit: 3286222fc609dea27bd16ac02c55d3f1c3190063 ("mm, slub: better heuristic for number of cpus when calculating slab order")
https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git master
in testcase: stress-ng
on test machine: 96 threads Intel(R) Xeon(R) Gold 6252 CPU @ 2.10GHz with 512G memory
with following parameters:
nr_threads: 100%
disk: 1HDD
testtime: 60s
sc_pid_max: 4194304
class: scheduler
test: vfork
cpufreq_governor: performance
ucode: 0x5003003
Details are as below:
