Speed crown changes hands: Safari 4 slows down, now behind Chrome
Perhaps the absence of Apple CEO Steve Jobs, or any hint of his existence, will go down as the biggest disappointment of this year's WWDC conference in San Francisco. But it may be on the top of a list of more than one item, and down that list not too far behind Jobs' no-show, there is this news: The final release version of Safari 4 is not the fastest Web browser on Windows, despite what SVP Phil Schiller told attendees today.
But in an amazing change of fortune for Apple, Safari 4 on Vista SP2 slowed down dramatically by 20%, meeting the Win7 figures halfway. In Betanews tests this afternoon, Safari 4 posted a performance index score of 12.11 in Vista SP2, tucking the new browser back in third position behind the stable release of Google Chrome 220.127.116.11 at 12.23, and 12.24 for the beta release of Chrome 18.104.22.168.
And while Safari 4 now runs 13% faster on Win7 than on Vista, instead of the other way around, its index score now falls behind Chrome 2 by mere hundredths: a 13.41 versus Chrome 2's 13.43 and Chrome 3's 13.86. This despite Chrome 2 and Safari 4 posting 100% scores on the Acid3 standards compliance test, which makes up 25% of our index score.
Safari 4 can still claim about 45% better performance in Win7 than the browser that could be released to the public this week as Firefox 3.5 RC, which posted a 9.23 index score in Betanews tests this morning. And Safari 4 is almost six times the browser that Internet Explorer 8 is, in terms of speed and performance. But in what has become one of the most exciting and competitive races since the early '90s, at the moment, it's Chrome by a nose.
