Subject: [linus:master] [sched/fair] 86bfbb7ce4:
fxmark.ssd_ext4_dbench_client_2_directio.works/sec -15.5% regression
Hello,
kernel test robot noticed a -15.5% regression of fxmark.ssd_ext4_dbench_client_2_directio.works/sec on:
commit: 86bfbb7ce4f67a88df2639198169b685668e7349 ("sched/fair: Add lag based placement")
https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git master
testcase: fxmark
test machine: 128 threads 2 sockets Intel(R) Xeon(R) Platinum 8358 CPU @ 2.60GHz (Ice Lake) with 128G memory
parameters:
disk: 1SSD
