Subject: [thp] db001b7115: vm-scalability.median 8.9% improvement
Greeting,
FYI, we noticed a 8.9% improvement of vm-scalability.median due to commit:
commit: db001b7115ac61820c5bc44994537bef3853bac6 ("[PATCHv2 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/20200405-000201
base: https://git.kernel.org/cgit/linux/kernel/git/shuah/linux-kselftest.git next
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/
Details are as below:
