- Accurate Metrics: Reports detailed performance data including throughput, loss, and jitter.
- Enhanced Reliability: Offers improved accuracy over older versions like iPerf2.
- Authentication Support: Available builds with authentication features for secure testing.
- Cross-Platform Compatibility: Works across various operating systems and kernels.
Audience & Benefit: Ideal for network engineers, IT professionals, and researchers needing precise network performance insights. iPerf3 helps in identifying bottlenecks and validating network configurations, thereby optimizing overall network efficiency.
iPerf3 can be installed via winget on supported platforms, ensuring ease of use without the need for direct downloads.
README
iperf3 - binaries for windows
Benchmark your network limits
Intro
iperf3 can be used to measure maximum network throughput. 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.
Last 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 before upload.
