Browser Sunspider update
IEBlog recently showed some Sunspider results that show them currently ahead of us. I just want to correct that a little bit. :-)
The latest Firefox shown on their graph is Firefox 4.0 beta 6, which is well behind our nightly releases at this point, including in performance. Their graph shows the Chrome 8 nightly, but nightlies for no other browsers. So I decided to do a comparison test using Sunspider 0.9.1 on the latest version I could get for each of the big 5 browsers. Results:
So, not terribly different from their results, except that it shows we’re a hair faster as of now, at least on this machine. We are currently finishing up a last few perf projects before we turn to focus on getting it ready for release. I’m expecting us to get 3-10% faster by then, but that’s just a guess. I’m sure IE is still working on perf as well.
A final point is that the graph shows pretty clearly that Sunspider scores are converging: the days when one browser would be 2x or 6x as fast as another are gone. Now it’s more like 1.1x or 1.2x. I know there are a few more tricks we can play that are too complicated to do before Firefox 4.0, but they would make only a small dent in Sunspider scores. By next year, either we’ll all be fast and basically done with JS perf work, or else it will be time to update the benchmark to help drive the next round of perf improvments.
Update: sdwilsh pointed out to me that the IEBlog post shows a date of “10/25″ for Firefox, which isn’t the build date of beta 6. So it might actually be a nightly build from a week or two ago. Not clear.
