Subject: [linus:master] [mm]  9cee7e8ef3:  netperf.Throughput_Mbps 4.0%
 improvement



hi, Yosry Ahmed,

we shared the performance impact of this commit in
https://lore.kernel.org/lkml/ZbDJsfsZt2ITyo61@xsang-OptiPlex-9020/

now we noticed the commit is merged in mainline, and we observed improvements
in other performance tests such like netperf and stress-ng.
the vm-scalability and will-it-scale results are also included FYI.


Hello,

kernel test robot noticed a 4.0% improvement of netperf.Throughput_Mbps on:


commit: 9cee7e8ef3e31ca25b40ca52b8585dc6935deff2 ("mm: memcg: optimize parent iteration in memcg_rstat_updated()")
https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git master

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

	ip: ipv4
	runtime: 300s
	nr_threads: 200%
	cluster: cs-localhost
	send_size: 10K
	test: TCP_SENDFILE
	cpufreq_governor: performance


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