Hi Team,

While going through Blink's comment, I came across following commit:

Blink Commit - https://src.chromium.org/viewvc/blink?view=revision&revision=181053

Wayback Archive URL for Benchmark - https://web.archive.org/web/20211017201144/https://testdrive-archive.azurewebsites.net/Performance/Pirates/Default.html

^ Safari 16.1 - 96.74 seconds (STP 159 - 79.50 - slightly faster)
Chrome Canary 110 - 4.50 seconds
Firefox Nightly 109 - 5.19 seconds

Just wanted to raise this bug since Safari is significantly slower.

Thanks!

@Nikolas - can you try with LBSE turned on whether it makes a difference on this benchmark / improve performance?

I don't think LBSE will affect this.

It is now very stutters in WebKit ToT (269488@main).

@Simon - Could this be regressed due to latest changes around Filters?

I doubt it got worse. Lots of time under FETurbulenceSoftwareApplier.

It is bad but Safari 17 is bit smoother compared to WebKit ToT. WebKit ToT has more stutters (at least on my system).
