Date: Wed, 31 Jan 2024 23:17:57 +0800 [thread overview]
Message-ID: <202401312212.f0f4517c-oliver.sang@intel.com> (raw)
Hello,
kernel test robot noticed a -6.8% regression of stress-ng.sync-file.ops_per_sec on:
commit: 5e887f00379ac36883e4ef0ef418b2401686ebc9 ("pcp alloc opt")
https://github.com/gestionlin/linux.git page_frag_v3_0113
testcase: stress-ng
test machine: 64 threads 2 sockets Intel(R) Xeon(R) Gold 6346 CPU @ 3.10GHz (Ice Lake) with 256G memory
parameters:
nr_threads: 10%
