" iperf is a tool for active measurements of the maximum achievable bandwidth on IP networks. It supports tuning of various parameters related to timing, protocols, and buffers. For each test it reports the measured throughput / bitrate, loss, and other parameters. "
I do not develop Iperf. For more information see the : https://software.es.net/iperf
You first need to install the iperf3 library available on the ENSET Github. I advise you to build it as it is described in the repo. If you have not installed the library, the Go compiler will not find #cgo LDFLAGS: -liperf
Just run
$ go get github.com/lthomasmp/iperf_goTo test the wrapper, just run the example. This example use your local IP address.
$ cd examples
$ go build ClientServerExample.go
$ ./ClientServerExample <your_port>
