Subject: [lkp-robot] [brd] 316ba5736c: aim7.jobs-per-min -11.2% regression
Greeting,
FYI, we noticed a -11.2% regression of aim7.jobs-per-min due to commit:
commit: 316ba5736c9caa5dbcd84085989862d2df57431d ("brd: Mark as non-rotational")
https://git.kernel.org/cgit/linux/kernel/git/axboe/linux-block.git for-4.18/block
in testcase: aim7
on test machine: 40 threads Intel(R) Xeon(R) CPU E5-2690 v2 @ 3.00GHz with 384G memory
with following parameters:
disk: 1BRD_48G
fs: btrfs
test: disk_rw
load: 1500
cpufreq_governor: performance
test-description: AIM7 is a traditional UNIX system level benchmark suite which is used to test and measure the performance of multiuser system.
test-url: https://sourceforge.net/projects/aimbench/files/aim-suite7/
Details are as below:
