iPerf3 is a tool for active measurements of the maximum achievable bandwidth on IP networks. It supports tuning of various parameters related to timing, buffers and protocols (TCP, UDP, SCTP with IPv4 and IPv6). For each test it reports the bandwidth, loss, and other parameters. For more information, see the iperf repo, which also includes the iperf3 source code (note that this repository does not include any iperf3 source code). In general, the app is capable of: perform simple iperf3 upload and download tests Save preconfigured; Save test results; Graph transfer and bitrate; This application does not share your personal data or geolocation, all work is offline.
