There are many different open source licenses but they all must comply with the Open Source Definition - in brief: the software can be freely used, modified and shared. Programs released under this license can be used at no cost for both personal and commercial purposes. Open Source software is software with source code that anyone can inspect, modify or enhance. Freeware products can be used free of charge for both personal and professional (commercial use). New: Disk write tests (server: iperf3 -s -F filename / client: iperf3 -c testhost -i1)Īlso Available: Download Iperf for Windowsįreeware programs can be downloaded used free of charge and without any time limitations.New: Disk read test (server: iperf3 -s / client: iperf3 -c testhost -i1 -F filename).New: Output in JSON format (-J option).New: Use SCTP rather than TCP (-sctp option).New: Set congestion control algorithm (-C option).New: Set target bandwidth for UDP and (new) TCP (-b option).A server accepts a single client simultaneously (iPerf3) multiple clients simultaneously (iPerf2).Use representative streams to test out how link layer compression affects your achievable bandwidth (-F option).Print periodic, intermediate bandwidth, jitter, and loss reports at specified intervals (-i option).Can run for specified time (-t option), rather than a set amount of data to transfer (-n or -k option).Server handles multiple connections, rather than quitting after a single test.Client and server can have multiple simultaneous connections (-P option).Client can create UDP streams of specified bandwidth.Support for TCP window size via socket buffers.Report MSS/MTU size and observed read sizes.This is a new implementation that shares no code with the original iPerf for macOS and also is not backwards compatible. For each test it reports the bandwidth, loss, and other parameters. It supports tuning of various parameters related to timing, buffers and protocols (TCP, UDP, SCTP with IPv4 and IPv6).
