According to a pprof, creating RTCCodecStats is one of the places where we spend the most CPU time in the event of creating hundreds of them: https://screenshot.googleplex.com/B6QNDvvoX8dK5vk The lifetime was recently updated so that we no longer have to risk creating hundreds of them, here is the relevant section: https://w3c.github.io/webrtc-stats/#codec-dict* This allows code simplifications and the deletion of ProduceCodecStats_n since we can now do a lazy instantiation of codec stats at the point of being referenced.

WebRTC is a free, open software project that provides browsers and mobile applications with Real-Time Communications (RTC) capabilities via simple APIs. The WebRTC components have been optimized to best serve this purpose.
Our mission: To enable rich, high-quality RTC applications to be developed for the browser, mobile platforms, and IoT devices, and allow them all to communicate via a common set of protocols.
The WebRTC initiative is a project supported by Google, Mozilla and Opera, amongst others.
Development
