Subject: [mm] 9266baf8ee: vm-scalability.median -17.0% regression
Greeting,
FYI, we noticed a -17.0% regression of vm-scalability.median due to commit:
commit: 9266baf8eea588a78e5a0aa4ccd6cae36ff7349d ("mm: Optimized hugepage zeroing & copying from user")
url: https://github.com/0day-ci/linux/commits/UPDATE-20200501-184514/Prathu-Baronia/mm-Optimized-hugepage-zeroing-copying-from-user/20200415-041712
in testcase: vm-scalability
on test machine: 16 threads Intel(R) Xeon(R) E-2278G CPU @ 3.40GHz with 32G memory
with following parameters:
runtime: 300s
size: 8T
test: anon-w-seq-hugetlb
cpufreq_governor: performance
ucode: 0xca
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.
