Iperf is an open-source network testing application used to measure the maximum available bandwidth between two endpoints in a network. It is commonly used to troubleshoot and diagnose network performance issues. It can be used to measure the throughput of a single connection, or it can be used to measure the throughput of multiple connections simultaneously. With Iperf, users can also measure the packet loss and jitter on a network connection. Additionally, Iperf can measure the network's delay and packet size. It is available for Windows, Mac, Linux, and Android platforms.
