            Bug ID: 248604
           Summary: Slow performance in Lite Brite Performance IE Test
                    Drive benchmark compared to others
           Product: WebKit
           Version: Safari Technology Preview
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2

Hi Team,

Similar to Bug 248602, we are also slower in following Benchmark:

Benchmark Link - (Selected - All) - https://testdrive-archive.azurewebsites.net/Performance/LiteBrite/Default.html

--> Safari 16.1 - 16.4 seconds
--> Chrome Canary 110 - 11.74 seconds
--> Firefox Nightly 109 - 9.74 seconds
--> STP 159 - 16 seconds (with Private Window)

As can be seen, we are up to approx. 5 seconds slower than other browsers, it is just synthetic benchmark so it might not matter but it might be used to identify any slow path in Safari / Webkit, which can be optimised to get better performance in real-world websites.

Just wanted to raise this bug, so it can be investigated. I have seen Blink / Chrome do some fixes for this benchmark but if I come across, I will post related bug details here.

Thanks!
