Subject: [thp] fd80f22b29: vm-scalability.median 10.3% improvement
Greeting,
FYI, we noticed a 10.3% improvement of vm-scalability.median due to commit:
commit: fd80f22b2954c87d04f4ad5574821948856fb382 ("[PATCHv4 7/8] thp: Change CoW semantics for anon-THP")
url: https://github.com/0day-ci/linux/commits/Kirill-A-Shutemov/thp-khugepaged-improvements-and-CoW-semantics/20200417-033525
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-cow-seq
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.
test-url: https://git.kernel.org/cgit/linux/kernel/git/wfg/vm-scalability.git/
In addition to that, the commit also has significant impact on the following tests:
