Subject: [thp] 3917c80280: vm-scalability.throughput 10.8% improvement
Greeting,
FYI, we noticed a 10.8% improvement of vm-scalability.throughput due to commit:
commit: 3917c80280c93a7123f1a3a6dcdb10a3ea19737d ("thp: change CoW semantics for anon-THP")
https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git master
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:
-------------------------------------------------------------------------------------------------->
To reproduce:
git clone https://github.com/intel/lkp-tests.git
cd lkp-tests
bin/lkp install job.yaml # job file is attached in this email
bin/lkp run job.yaml
