Description Jaya Allamsetty 2021-10-14 16:48:44 PDT

The peerconnection renegotiation timing has drastically increased in STP Release 133 (Safari 15.4, WebKit 16613.1.2.2) when compared to Safari 15.0 (16612.1.29.41.4, 16612).

Steps to reproduce
1. Go to https://webrtc.github.io/samples/src/content/peerconnection/negotiate-timing/.
2. Click on start->call->renegotiate with the number of video sections set to 100.
3. Compare the log that prints the time taken for negotiating from 1 to 100 video transceivers.

For Safari 15.0, it is around 633ms and on STP 133 it is 57040ms.

Updating libwebrtc to M96 at https://bugs.webkit.org/show_bug.cgi?id=232873 should fix the performance regression.
