    I was wondering if Safari was any faster under iOS 8 than 7, and by this I mean the javascript engine.
    Here are a few benchmarks you can run:

    Mozilla Kraken v 1.1:
    Sunspider v1.0:
    and results for comparison with iOS 7:

    Close all other apps, and all the tabs, clear safari cache (by changing to private mode and back), plug it in (so power doesn't affect cpu frequency), and don't touch the screen while the benchmark is running. Once that done, take a screen shot, and post it here along with the device name and screenshot.

    Why ask this before the final release? The performance could go as far as double by the final release if there are bad enough bugs in the beta OS which make it that slow. I'm not saying there are really bugs that bad, but still, apple still may not have optimized iOS 8 so it might not be up to speed.

    Because Javascript performance improvements have pretty much stopped recently, if there is any, I expect it to be within 10% for common string operations and array manipulation. Although they might choose to not touch safari at all.
    Edit: Actually they might have room for improvement, since this benchmark shows that safari (for desktop which shares many aspects with mobile safari, most notably the webkit engine) is slower than IE, Opera, FF, and Chrome in different JS benchmarks.

    I'm curious as well...

    You can always test a beta or even alpha at least to see the progress while reaching the final of course by knowing that its just alpha or beta.

    So if someone can do these tests that'd be cool.
