Subject: [ext4]  57e8668f62:  aim7.jobs-per-min 60.2% improvement



Greeting,

FYI, we noticed a 60.2% improvement of aim7.jobs-per-min due to commit:


commit: 57e8668f62e2f2fb09bc459d660f2af04aad9255 ("[PATCH v3 4/4] ext4: drop unnecessary journal handle in delalloc write")
url: https://github.com/0day-ci/linux/commits/Zhang-Yi/ext4-improve-delalloc-buffer-write-performance/20210718-105534
base: https://git.kernel.org/cgit/linux/kernel/git/tytso/ext4.git dev

in testcase: aim7
on test machine: 88 threads 2 sockets Intel(R) Xeon(R) Gold 6238M CPU @ 2.10GHz with 128G memory
with following parameters:

	disk: 4BRD_12G
	md: RAID1
	fs: ext4
	test: disk_rw
	load: 3000
	cpufreq_governor: performance
	ucode: 0x5003006

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/

In addition to that, the commit also has significant impact on the following tests:
