Subject: [lkp-robot] [sched/fair] 806486c377: fsmark.app_overhead 39.4%
improvement
Greeting,
FYI, we noticed a 39.4% improvement of fsmark.app_overhead due to commit:
commit: 806486c377e33ab662de6d47902e9e2a32b79368 ("sched/fair: Do not migrate if the prev_cpu is idle")
https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git master
in testcase: fsmark
on test machine: 4 threads Intel(R) Core(TM) i5-2300 CPU @ 2.80GHz with 4G memory
with following parameters:
iterations: 1x
nr_threads: 32t
disk: 1HDD
fs: ext4
filesize: 16MB
test_size: 60G
sync_method: fsyncBeforeClose
nr_directories: 16d
nr_files_per_directory: 256fpd
cpufreq_governor: performance
test-description: The fsmark is a file system benchmark to test synchronous write workloads, for example, mail servers workload.
test-url: https://sourceforge.net/projects/fsmark/
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
