The receiver is started first and waits for a connection. Once the two connect, the sending machine sends data to the receiver and displays the overall throughput of the network they traverse. The amount of data sent and other options are configurable through command line parameters.
iperf, Iperf, or iPerf, is a tool for network performance measurement and tuning. It is a cross-platform tool that can produce standardized performance measurements for any network. iperf has client and server functionality, and can create data streams to measure the throughput between the two ends in one or both directions.

Netperf is a software application that provides network bandwidth testing between two hosts on a network. It supports Unix domain sockets , TCP , SCTP , DLPI and UDP via BSD Sockets. [ 1 ] Netperf provides a number of predefined tests e.g. to measure bulk (unidirectional) data transfer or request response performance.
People are often concerned about measuring the maximum data throughput in bits per second of a communications link or network access. A typical method of performing a measurement is to transfer a 'large' file from one system to another system and measure the time required to complete the transfer or copy of the file.
It supports hardware performance counters, tracepoints, software performance counters (e.g. hrtimer), and dynamic probes (for example, kprobes or uprobes). [4] In 2012, two IBM engineers recognized perf (along with OProfile ) as one of the two most commonly used performance counter profiling tools on Linux.
vnStat, useful command to monitor network traffic from the console. vnstat allows to keep the traffic information in a log system to be analyzed by third party tools. Other network utilities include: netstat, displays network connections (both incoming and outgoing), routing tables, and a number of network interface and network protocol ...

All of the factors above, coupled with user requirements and user perceptions, play a role in determining the perceived 'fastness' or utility, of a network connection. The relationship between throughput, latency, and user experience is most aptly understood in the context of a shared network medium, and as a scheduling problem.
