Subject: [linus:master] [maple_tree] 59faa4da7c:
will-it-scale.per_process_ops 20.4% regression
Hello,
kernel test robot noticed a 20.4% regression of will-it-scale.per_process_ops on:
commit: 59faa4da7cd4565cbce25358495556b75bb37022 ("maple_tree: use percpu sheaves for maple_node_cache")
https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git master
[still regression on linus/master e406d57be7bd2a4e73ea512c1ae36a40a44e499e]
[still regression on linux-next/master 7396732143a22b42bb97710173d598aaf50daa89]
testcase: will-it-scale
config: x86_64-rhel-9.4
compiler: gcc-14
test machine: 192 threads 2 sockets Intel(R) Xeon(R) Platinum 8468V CPU @ 2.4GHz (Sapphire Rapids) with 384G memory
parameters:
nr_task: 100%
mode: process
test: brk1
cpufreq_governor: performance
