Subject: [linus:master] [mm, mmap] d4148aeab4: will-it-scale.per_process_ops
3888.9% improvement
Hello,
kernel test robot noticed a 3888.9% improvement of will-it-scale.per_process_ops on:
commit: d4148aeab412432bf928f311eca8a2ba52bb05df ("mm, mmap: limit THP alignment of anonymous mappings to PMD-aligned sizes")
https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git master
[test failed on linux-next/master 5b913f5d7d7fe0f567dea8605f21da6eaa1735fb]
testcase: will-it-scale
config: x86_64-rhel-8.3
compiler: gcc-12
test machine: 224 threads 4 sockets Intel(R) Xeon(R) Platinum 8380H CPU @ 2.90GHz (Cooper Lake) with 192G memory
parameters:
nr_task: 100%
mode: process
test: malloc1
cpufreq_governor: performance
In addition to that, the commit also has significant impact on the following tests:
+------------------+---------------------------------------------------------------------------------------------+
| testcase: change | stress-ng: stress-ng.radixsort.ops_per_sec 9.2% regression |
| test machine | 224 threads 2 sockets Intel(R) Xeon(R) Platinum 8480CTDX (Sapphire Rapids) with 256G memory |
