Subject: [lkp] [mm] 371a096edf: vm-scalability.throughput 6.1% improvement
Greeting,
FYI, we noticed a 6.1% improvement of vm-scalability.throughput due to commit:
commit 371a096edf43a8c71844cf71c20765c8b21d07d9 ("mm: don't use radix tree writeback tags for pages in swap cache")
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git master
in testcase: vm-scalability
on test machine: 72 threads Intel(R) Xeon(R) CPU E5-2699 v3 @ 2.30GHz with 128G memory
with following parameters:
runtime: 300
thp_enabled: never
thp_defrag: never
nr_task: 16
nr_ssd: 1
test: swap-w-seq
cpufreq_governor: performance
The motivation behind this suite is to exercise functions and regions of the mm/ of the Linux kernel which are of interest to us.
In addition to that, the commit also has significant impact on the following tests:
+------------------+-----------------------------------------------------------------------+
| testcase: change | vm-scalability: vm-scalability.throughput 14.1% improvement |
| test machine | 72 threads Intel(R) Xeon(R) CPU E5-2699 v3 @ 2.30GHz with 128G memory |
| test parameters | cpufreq_governor=performance |
| | nr_ssd=1 |
| | nr_task=64 |
| | runtime=300 |
| | test=swap-w-seq |
| | thp_defrag=never |
| | thp_enabled=always |
+------------------+-----------------------------------------------------------------------+
