Subject: [LKP] [net/sock]  b99259a614:  netperf.Throughput_Mbps -6.6%
 regression

Greeting,

FYI, we noticed a -6.6% regression of netperf.Throughput_Mbps due to commit:


commit: b99259a61450bb6403bbbbf279f8754a441eae8b ("[PATCH] net/sock: move memory_allocated over to percpu_counter variables")
url: https://github.com/0day-ci/linux/commits/Olof-Johansson/net-sock-move-memory_allocated-over-to-percpu_counter-variables/20180907-095536


in testcase: netperf
on test machine: 8 threads Intel(R) Core(TM) i7-4770 CPU @ 3.40GHz with 8G memory
with following parameters:

	ip: ipv4
	runtime: 300s
	nr_threads: 200%
	cluster: cs-localhost
	send_size: 5K
	test: TCP_SENDFILE
	ucode: 0x25
	cpufreq_governor: performance

test-description: Netperf is a benchmark that can be use to measure various aspect of networking performance.
test-url: http://www.netperf.org/netperf/

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