iPerfBox

iPerfBox is a lightweight network throughput tester that embeds the standard open-source iperf2 and iperf3 engines directly into the app and runs them in-process — no command-line tools to install on your device. Features: • Both iperf2 and iperf3 built in, switch with one tap • TCP and UDP, with an optional target bandwidth for UDP • Set server address, port and test duration • Forward / reverse test (measure uplink or downlink) • Custom-arguments mode: type a full iperf command line for advanced use • Live iperf output log with selectable text Great for verifying LAN bandwidth, troubleshooting Wi-Fi coverage, testing routers and NAS throughput, and field network diagnostics. Requirements: you need a reachable iperf server (run iperf3 -s on any computer). This app is a client, collects no personal data, and connects only to the server you specify.
