Subject: [sched/numa] 6942795656: fio.read_bw_MBps -37.5% regression
Greeting,
FYI, we noticed a -37.5% regression of fio.read_bw_MBps due to commit:
commit: 6942795656e5c8906b059622a23352a2e3c38d06 ("sched/numa: Replace runnable_load_avg by load_avg")
https://github.com/0day-ci/linux/commits/UPDATE-20200221-072833/Vincent-Guittot/remove-runnable_load_avg-and-improve-group_classify/20200217-172341
in testcase: fio-basic
on test machine: 96 threads Intel(R) Xeon(R) Gold 6252 CPU @ 2.10GHz with 256G memory
with following parameters:
disk: 2pmem
fs: ext4
mount_option: dax
runtime: 200s
nr_task: 50%
time_based: tb
rw: read
bs: 2M
ioengine: libaio
test_size: 200G
cpufreq_governor: performance
ucode: 0x500002c
test-description: Fio is a tool that will spawn a number of threads or processes doing a particular type of I/O action as specified by the user.
