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.

nuttcp is a network performance measurement tool intended for use by network and system managers. Its most basic usage is to determine the raw TCP (or UDP) network layer throughput by transferring memory buffers from a source system across an interconnecting network to a...
Netperf is a benchmark that can be used to measure the performance of many different types of networking. It provides tests for both unidirectional throughput, and end-to-end latency.
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.
LANBench is a simple LAN / TCP Network benchmark utility. It is designed for testing network performance between two computers and is based on Winsock 2.2. LANBench tests TCP performance only and is designed for minimal CPU usage so that the pure performance of your network...
