Gonetp is a multi-core netperf, written in Go. It was originally written to evaluate the performance of the Akaros networking stack. It can also be ran on Linux.

These instructions assume you have a proper GOPATH setup, and that $GOPATH/bin is in your path. Instructions for setting up your GOPATH can be found here: https://github.com/golang/go/wiki/GOPATH

go get github.com/klueska/gonetp/gonetp-server
go get github.com/klueska/gonetp/gonetp-client

Start the server on one machine:

gonetp-server

And the client on another

gonetp-client -H=<server_ip>

And read the results (this could use some cleaning up...):
