Introduction​

In the world of real-time communication, performance is paramount. WebRTC has become the standard for peer-to-peer audio, video, and data transfer. While the browser implementations are well-known, server-side and native implementations are crucial for building scalable infrastructure, gateways, and high-performance clients.

This article presents a performance benchmark comparing three prominent WebRTC implementations, with the code available at restsend/rustrtc:

  1. RustRTC: A pure Rust implementation of WebRTC (the project under test).
  2. webrtc-rs: The most popular Rust implementation (a port of Pion).
  3. Pion: The industry-standard Go implementation of WebRTC.
