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:
