iperf

iPerf is a network testing tool used to measure the performance of internet connections. It evaluates bandwidth, latency, and data transfer rates between two devices connected over a network. By setting one device as a server and another as a client, iPerf can simulate data traffic to see how well the connection performs under different conditions. It helps diagnose network issues or improve configurations by providing detailed metrics, making it useful for IT professionals and anyone needing to ensure their network is running efficiently.
