goben is described as 'golang tool to measure TCP/UDP transport layer throughput between hosts. goben is intended to fix shortcomings of other network performance tools: 1) Take advantage of multiple CPUs while not wasting processing power'. There are five alternatives to goben for a variety of platforms, including Windows, Linux, Mac, Solaris and FreeBSD. The best alternative is iPerf3, which is both free and Open Source. Other great apps like goben are nuttcp (Free, Open Source), netperf (Free, Open Source), TamoSoft Throughput Test (Free) and NetStress (Free).
The iperf series of tools perform active measurements to determine 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, loss, and other parameters.
A utility for testing the performance of a wireless or wired network that sends TCP and UDP data streams and computes important metrics: upstream and downstream throughput values, packet loss, and round-trip time, etc. It supports both IPv4 and IPv6 connections.
