[linux-next:master] [mm] 98c9daf5ae: aim7.jobs-per-min -29.4% regression

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 




Hello,

kernel test robot noticed a -29.4% regression of aim7.jobs-per-min on:


commit: 98c9daf5ae6be008f78c07b744bcff7bcc6e98da ("mm: memcg: guard memcg1-specific members of struct mem_cgroup_per_node")
https://git.kernel.org/cgit/linux/kernel/git/next/linux-next.git master

testcase: aim7
test machine: 128 threads 2 sockets Intel(R) Xeon(R) Gold 6338 CPU @ 2.00GHz (Ice Lake) with 256G memory
parameters:

	disk: 1BRD_48G
	fs: ext4
	test: disk_rr
	load: 3000
	cpufreq_governor: performance


some further information.

we don't have CONFIG_MEMCG_V1 in our config which is uploaded to [1]
# CONFIG_MEMCG_V1 is not set

we also tried to capturing perf-c2c data in the whole process of this benchmark.
got below:
