Abstract —Network performance testing is critical for infrastructure validation. Iperf3 is the industry standard for measuring maximum TCP/UDP throughput, but it lacks a native, modern graphical user interface (GUI) on Windows platforms. This paper presents Iperf3-Cygwin-GUI , a wrapper application that leverages the Cygwin POSIX emulation layer to execute Iperf3 on Windows while providing a real-time, interactive dashboard. We discuss the architectural challenges of bridging a Windows GUI (C#/WPF) with a Cygwin-based process, the implementation of real-time stream parsing, and performance benchmarks comparing the GUI overhead against native CLI execution. Results show that the GUI introduces less than 2% CPU overhead and no measurable impact on throughput accuracy. if (data
