It allows to calibrate several parameters like timing, buffers, protocols and streams that can help in network optimization. Each test shows various network performance metrics including throughput, jitter and packet loss. iperf3 results are considered much more accurate and reliable.  \n\nLast official binary release version was 3.1.3 for Windows in 2016 . This repo is created for iperf3 pre-compiled binaries for Windows. **The goal is to create iperf3 Windows executable without any modification in original source code.** Each binary released is checked with [VirusTotal](https://www.virustotal.com/gui/home/upload) before upload.  \n\n#\n### Builds\n|iperf Ver    |Cygwin Ver      |OS          |OpenSSL Ver|\n|:-----------:|:--------------:|:----------:|:---------:|\n|3.18         |3.5.4-1.x86_64  |Win11 64-bit|3.0.15     |\n|3.17.1       |3.5.3-1.x86_64  |Win11 64-bit|3.0.13     |\n|3.16         |3.4.10-1.x86_64 |Win11 64-bit|3.0.12     |\n\n#### Benchmark\n* Many folks use iperf to evaluate internet speed.
