Subject: [lkp] [fs] 27a23abdf6: vm-scalability.throughput 44.7% improvement
Greeting,
FYI, we noticed a 44.7% improvement of vm-scalability.throughput due to commit:
commit 27a23abdf63184c5853c6e5004cf584b880d26fb ("fs: only set S_VERSION when updating times if it has been queried")
git://git.samba.org/jlayton/linux iversion
in testcase: vm-scalability
on test machine: 4 threads Intel(R) Core(TM) i3-3220 CPU @ 3.30GHz with 8G memory
with following parameters:
runtime: 300s
size: 1T
test: msync-mt
cpufreq_governor: performance
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 git://git.kernel.org/pub/scm/linux/kernel/git/wfg/lkp-tests.git
cd lkp-tests
bin/lkp install job.yaml # job file is attached in this email
bin/lkp run job.yaml
