Hello,
kernel test robot noticed a 53.9% improvement of vm-scalability.throughput on:
commit: 66987218154918a6341a3e3eeeee58110a69e0bb ("mm/page_alloc: ignore the exact initial compaction result")
https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git master
testcase: vm-scalability
config: x86_64-rhel-9.4
compiler: gcc-14
test machine: 512 threads 4 sockets Intel(R) Xeon(R) 6768P CPU @ 2.4GHz (Granite Rapids) with 128G memory
parameters:
runtime: 300s
test: lru-file-mmap-read
cpufreq_governor: performance
In addition to that, the commit also has significant impact on the following tests:
