How to Reduce WebRTC Latency: A Production Engineering Guide
15 min read readPractical techniques for achieving low end-to-end latency in WebRTC applications, from codec selection to edge deployment and congestion control tuning.
Latency in WebRTC is cumulative: capture, encoding, network transit, jitter buffer, decode, and render. This guide breaks down each stage and provides optimization strategies. Topics include codec selection tradeoffs (AV1, VP9, H.264), edge SFU placement, kernel networking tuning, jitter buffer minimization, and interpreting Chrome's webrtc-internals to identify whether a bottleneck is local or network-bound.
