by ATH Infosystems

Version 3.20 + Free Support on Ubuntu 24.04

iPerf3 is a lightweight, accurate network performance measurement tool that tests TCP, UDP and SCTP throughput between hosts — ideal for benchmarking, troubleshooting, and capacity planning.

Features of iPerf3:

  • Measures TCP and UDP throughput with fine-grained control over test parameters.
  • Supports parallel streams and configurable bandwidth, packet size, and test duration.
  • Client–server architecture with reverse-mode testing (server sends to client).
  • Produces machine-readable JSON output for automated parsing and reporting.
  • Reports useful metrics: throughput, jitter, packet loss, retransmits, and latency statistics.
  • Cross-platform and open-source — runs on Linux, macOS, Windows, and many embedded systems.
  • Lightweight and scriptable, making it suitable for automated network validation and CI/CD pipelines.
