Scaling WebRTC Streams with Engine Pooling in Go
FATAL: crypto/rand: blocked on getrandom() syscall, or 100% CPU at the 25th Client The title is catchy enough—now let’s get to the point. This error is a classic side effect of the default Pion WebRTC setup in Go. It is easy to reproduce: you read the usual Pion usage guides, deploy a nice-looking WHEP handler, open a couple of—okay, okay, not literally a couple, just a figure of speech—browser…
Title: Scaling WebRTC Streams with Engine Pooling in Go
This article explains how to improve WebRTC performance in Go applications by using engine pooling. The performance issues arise from creating a new WebRTC instance for each incoming request, which leads to expensive operations like generating cryptographic material, allocating memory for multiple structures, and opening new UDP ports. The solution is to reuse the same WebRTC engine for multiple connections, reducing resource consumption and speeding up request responses.
