Greeting,
FYI, we noticed a 4.2% improvement of netperf.Throughput_tps due to commit:
commit 34630bc07341e30e42a974840a0d622b31f1845c ("inet: fix sleeping inside inet_wait_for_connect()")
https://github.com/0day-ci/linux Cong-Wang/inet-fix-sleeping-inside-inet_wait_for_connect/20161102-070925
in testcase: netperf
on test machine: 8 threads Intel(R) Atom(TM) CPU C2750 @ 2.40GHz with 16G memory
with following parameters:
ip: ipv4
runtime: 300s
nr_threads: 200%
cluster: cs-localhost
test: TCP_CRR
cpufreq_governor: performance
Netperf is a benchmark that can be use to measure various aspect of networking performance.
