kraken takes too long to complete, with any browser, + I suspect Mozilla of having optimized Kraken for Firefox
>>> some of them (@ Mozilla) are already saying that sunspider is not relable
Firefox 4.0b7pre is actually performing better now, on Sunspider, as I mentioned in my first post here, but the problem is that it's still browsing the web slowly (when compared to Chrome, Opera or IE9)...which make me wonder about the tricks they may have used to fool sunspider...just guessing, this is really weird.
edit: we're talking about speed and performance in general here, not security, and not "noscript".
