Rust WebRTC SFU Latency Cut from 70 ms to 10 ms Using Thread‑Per‑Core Design

A recent blog post details a performance overhaul of a Rust WebRTC SFU. The author migrated the server architecture to a thread‑per‑core model. This change reduced the 99.99th percentile latency from 70 ms to 10 ms. The improvement demonstrates the benefits of fine‑grained concurrency in Rust. The SFU now handles media streams with significantly lower delay. The author provides benchmarks and implementation notes for developers. The technique may be adopted by other real‑time communication projects. Readers are encouraged to review the full blog for technical details.
