Great performance improvements coming for Firefox 3.1
20 August 2008We know one of the things folks love about Firefox 3 is the huge performance improvements made over Firefox 2. We knew we could do a whole lot more – which is one of the reasons we decided to do a quick Firefox 3.1 release.
Boris Zbarsky landed support for querySelector[All] just before Firefox 3.1 Alpha 1. Recently John Resig and Mike Morgan took the slickspeed selectors test from the Mootools project and updated it with versions of most of the toolkits that support native querySelector.
The results are an impressive ~3-7x speedup!
The raw times looks like thus:
You can try it yourself here (make sure to use a Firefox 3.1 alpha or nightly build after July 22). Since all major browsers will soon support this feature the entire web is about to get a pretty big performance boost.
More great stuff is on the way for Firefox 3.1…
