Subject: [lkp] [net] 9863a93605: netpipe.bigger_5M_Mbps.avg -80.0%
regression
FYI, we noticed a -80.0% regression of netpipe.bigger_5M_Mbps.avg due to commit:
commit 9863a936051349cd921735b4c84eaa209de34c67 ("net: use non-compound pages in frag allocator")
https://github.com/0day-ci/linux Ilya-Lesokhin/net-use-non-compound-pages-in-frag-allocator/20160804-205029
in testcase: netpipe
on test machine: 48 threads 2 sockets Xeon E5 (Ivytown Ivy Bridge-EP) with 64G memory
with following parameters:
test: tcp
cluster: cs-localhost
cpufreq_governor: performance
