[lkp-robot] [mm/swap] 73c6573f40: vm-scalability.throughput 67.1% improvement
by kernel test robot
Greeting,
FYI, we noticed a 67.1% improvement of vm-scalability.throughput due to commit:
commit: 73c6573f407836b36bd8b2ebcd41895ffad4cca8 ("mm/swap: Split swap cache into 64MB trunks")
git://bee.sh.intel.com/git/yhuang/linux.git swap_optimize_v5.1
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:
thp_enabled: never
thp_defrag: never
nr_task: 32
disk: 1pmem
test: swap-w-seq
unit_size: 96G
size: 96G
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/
In addition to that, the commit also has significant impact on the following tests:
