Subject: [lkp-robot] [btrfs]  a9d3e24b6e:  aim7.jobs-per-min 19.9% improvement


Greeting,

FYI, we noticed a 19.9% improvement of aim7.jobs-per-min due to commit:


commit: a9d3e24b6e881c4a249eb9084328b096cfe1f8c4 ("btrfs: always wait on ordered extents at fsync time")
https://git.kernel.org/cgit/linux/kernel/git/next/linux-next.git master

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: 4BRD_12G
	md: RAID0
	fs: btrfs
	test: sync_disk_rw
	load: 20
	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.
