Greeting,
FYI, we noticed a -11.8% regression of vm-scalability.median due to commit:
commit: 1f7ab644d62fa532678e89e0a619d069b0a52f57 ("skip local node for multiple
threaded applications too")
git://bee.sh.intel.com/git/yhuang/linux.git autonuma5
in testcase: vm-scalability
on test machine: 88 threads Intel(R) Xeon(R) CPU E5-2699 v4 @ 2.20GHz with 128G memory
with following parameters:
runtime: 300s
size: 512G
test: anon-cow-rand
cpufreq_governor: performance
ucode: 0xb000036
test-description: The motivation behind this suite is to exercise functions and regions of
the mm/ of the Linux kernel which are of interest to us.
