Sign in to saveAlso known as iperf3
iperf, also known as 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. Typical iperf output contains a time-stamped report of the amount of data transferred and the throughput measured.

iperf, also known as 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. Typical iperf output contains a time-stamped report of the amount of data transferred and the throughput measured.
The data streams can be either Transmission Control Protocol (TCP) or User Datagram Protocol (UDP): UDP: When used for testing UDP capacity, iperf allows the user to specify the datagram size and provides results for the datagram throughput and the packet loss. TCP: When used for testing TCP capacity, iperf measures the throughput of the payload. iperf uses 1024 × 1024 for mebibytes and 1000 × 1000 for megabytes. iperf is open-source software written in C, and it runs on various platforms, including Linux, Unix and Windows (either natively or inside Cygwin). The availability of the source code enables the user to scrutinize the measurement methodology.
