docker-netperf

A docker image for netperf testing.

If the container is run without arguments, it will start a netserver daemon. The container also has the netperf client installed, so you can start another container to run the client.

Example

To compare throughput between Docker host networking and bridged networking:

$ # Run host-network netperf test
$ docker run -dt --net=host --name netserver-host paultiplady/netperf
$ docker run -it --net=host paultiplady/netperf netperf –l 10 -i 10 -I 95,1 -c -j -H 127.0.0.1 -t OMNI -- -D  -T tcp -O THROUGHPUT,THROUGHPUT_UNITS,STDDEV_LATENCY,LOCAL_CPU_UTIL
OMNI Send TEST from 0.0.0.0 (0.0.0.0) port 0 AF_INET to 127.0.0.1 () port 0 AF_INET : +/-0.500% @ 95% conf.  : nodelay
