Subject: [lkp] 64e3f9744b: reaim.jobs_per_min +34.3% improvement
FYI, we noticed a +34.3% improvement of reaim.jobs_per_min due to commit:
commit 64e3f9744bd3989457502ba79c09445a6909aac1 ("lockless next_positive()")
https://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs.git untested.dcache_readdir
in testcase: reaim
on test machine: lkp-hsw-ep2: 72 threads Brickland Haswell-EP with 128G memory
with following parameters: cpufreq_governor=performance/nr_task=1600%/runtime=300s/test=custom
In addition to that, the commit also has significant impact on the following tests:
reaim: reaim.jobs_per_min +78.6% improvement on test machine - lkp-hsw-ep2: 72 threads Brickland Haswell-EP with 128G memory
with test parameters: cpufreq_governor=performance/nr_job=3000/nr_task=100%/runtime=300s/test=custom
Details are as below:
