[mm/workingset] 170b04b7ae: vm-scalability.throughput 11.2% improvement
by kernel test robot
Greeting,
FYI, we noticed a 11.2% improvement of vm-scalability.throughput due to commit:
commit: 170b04b7ae49634df103810dad67b22cf8a99aa6 ("mm/workingset: prepare the workingset detection infrastructure for anon LRU")
https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git master
in testcase: vm-scalability
on test machine: 104 threads Skylake with 192G memory
with following parameters:
runtime: 300s
size: 1T
test: lru-shm
cpufreq_governor: performance
ucode: 0x2006906
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
