IE9 preview shows improved performance, still lags behind rivals (benchmarked)

It's finally here, and while it's not really a browser the technical preview of Internet Explorer 9 is now available for download from Microsoft. I've been curious how it would compare performance-wise with other browsers, and now I've got an early answer.

In short: it's better than IE8, but the IE9 preview still lags well behind its rivals.

In Peacekeeper, the IE9 preview scored 929 -- well up from the 580 posted by IE8 on my system. Still, that score is less than 1/3 those from Opera 10.50 and Chrome 5 and half that of Firefox 3.7. You can check out my graph in more detail here (note that Peacekeeper reports IE9 as IE8 on the chart).

The Acid3 result is better than IE8 as well, though the 55/100 is still well short of a respectable score.

It's important to note that this is a very early look at the upcoming browser, so there's still plenty of time for improvements to be made. Here's hoping Microsoft builds on what looks like a good start and delivers a browser that competes with the likes of Chrome, Opera, and Firefox.

Update: Non-scientific timings: IE9 loads Facebook.com in the same amount of time (+/-.05s) as Google Chrome 5. IE9 is 5 seconds slower loading GMail (can't say that's a surprise).
