Hello,
kernel test robot noticed a 8.1% improvement of stress-ng.pagemove.page_remaps_per_sec on:
commit: 0fc52deec1068ea3cc8eaa6e045c96fbf73f20e2 ("mm/slub: detach and reattach partial slabs in batch")
https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git master
testcase: stress-ng
config: x86_64-rhel-9.4
compiler: gcc-14
test machine: 192 threads 2 sockets Intel(R) Xeon(R) 6740E CPU @ 2.4GHz (Sierra Forest) with 256G memory
parameters:
nr_threads: 100%
testtime: 60s
test: pagemove
cpufreq_governor: performance
In addition to that, the commit also has significant impact on the following tests:
