Subject: [lkp-robot] [mm, memcontrol] 309fe96bfc: vm-scalability.throughput
+23.0% improvement
Greeting,
FYI, we noticed a +23.0% improvement of vm-scalability.throughput due to commit:
commit: 309fe96bfc0ae387f53612927a8f0dc3eb056efd ("mm, memcontrol: implement memory.swap.events")
https://git.kernel.org/cgit/linux/kernel/git/next/linux-next.git master
in testcase: vm-scalability
on test machine: 144 threads Intel(R) Xeon(R) CPU E7-8890 v3 @ 2.50GHz with 512G memory
with following parameters:
runtime: 300s
size: 1T
test: lru-shm
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:
