performance - How does BUNDLE help to improve webRTC connection/performance? By how much roughly?

Question

According to the doc here:

One obvious benefit of doing this is reducing the ICE negotiation time as the number of ICE candidates is reduced.

https://webrtcstandards.info/sdp-bundle/

BUNDLE is able to improve the performance. However, I fail to see how it can do so. Let's assume that this is the scenario I am in:

1. Forced TURN x 2 on some URL's 80 and 443 port
2. 1 to 1 connection. Let's not talk about conferencing situations.
3. Starting from scratch: ICE tricking, sdp offer... all the way to media stream in.
4. Audio and video goes 2 way.

I understand that bundle will mux audio and video into a single stream and send it over, so it can probably reduce the trickling time, at least by 1/2.

How about the part after sdp received by both parties and starts to send streams? Does it improve the connection time there too, compare to balance mode?

理论上，ICE 会调整用于连接检查的 stun 请求（隐藏在 RFC 5245 中的某处）。我强烈怀疑这是否有实际效果。

使用 bundle 的主要论点是您只需要在 NAT 中打一个洞，并且不会遇到音频打孔但视频没有打孔的奇怪情况。
