## What it is
A repository providing pre-compiled iperf3 Windows 64-bit executables, built via Cygwin without modifying the original source. It fills the gap left by the official iperf3 Windows binaries, which stopped at version 3.1.3 in 2016.

## Use cases
- measure maximum network throughput on windows
- test internet upload and download speed with iperf3
- run iperf3 server mode on windows 11
- benchmark network jitter and packet loss
- get an up-to-date iperf3 exe for windows
- run parallel stream network tests on win64

## When to choose
- you need current iperf3 binaries on Windows without compiling yourself
- you want VirusTotal-checked executables built from unmodified iperf3 source
- you need iperf3 authentication support or a Windows 7 build

## When to avoid
- you are on Linux or macOS where official iperf3 packages exist
- you need a GUI-based network testing tool
- you require modified or patched iperf3 builds

## Facets
- artifact type: application
- maturity: active
- function: benchmarking, networking, developer-tools
- domain: networking, developer-tools, windows, performance
- platform: windows, cli
- tags: iperf3, network-throughput, prebuilt-binaries, cygwin, win64, speed-test
