This page compares the WebRTC Round-Trip-Time calculated from getStats() to the time taken to process a ping/pong response pattern over websockets. It may not be a gold standard benchmark. Both WebRTC and Websockets have their merits/advantages which is why FastRTC supports both. Artifacts in the WebSocket playback audio are due to gaps in my frontend processing code and not FastRTC web server.
