Hi Team,
While just doing bit synthetic benchmark testings, I came across following:
Benchmark - https://testdrive-archive.azurewebsites.net/Performance/Popcorn/Default.html
Safari 16.1 (stutters visually and audio as well) - 8.11 seconds
Safari Technology Preview 159 (stutters visually and audio as well) - 7.17 seconds (6.66 in Private Mode) [I do have AdGuard installed]
Chrome Canary 110 - 1.79 seconds (no stutter)
Firefox Nightly 109 - 1.33 seconds (no stutter).
___
MacBook Pro 14 inch - M1 Pro - 16 GB - Baseline
___
I think we should investigate both audio stutter and slow performance as well.
Thanks!

NOTE - I selected "large" popcorn size.

I cannot reproduce that much of a difference with newer macOS/Safari on an Intel MacBook Pro, FWIW: Safari was 3.5 seconds, and Chrome was 2.5 seconds.
Looks like most time is spent in PlatformMediaSessionManager::maybeActivateAudioSession().

That was with default (medium) size. With large, I'm getting 9 seconds in Safari, and 3.5 in Chrome.
