Here's its description from GitHub: iperf is a tool for active measurements of the maximum achievable bandwidth on IP networks. It supports tuning various parameters related to timing, protocols, and buffers. Each test reports the measured throughput/bitrate, loss, and other parameters. freedom debt relief customer reviews https://conestogocraftsman.com
