How fast are we today? More and more web applications are using JavaScript to improve the UX (User eXperience) Almost all websites use frameworks like jQuery and mooTools, extJs etc. for this. So it is important that our browsers are fast with JavaScript!

Browsers are updated more often because they are more important every day. Since I have several extensions for Chrome and Firefox, it’s not fair to compare RAM usage. So I only looked at JavaScript performance. A way to compare it, is to run SunSpider http://www.webkit.org/perf/sunspider/sunspider.html

So I run all my installed browsers with my Centrino 2 cpu, win7sp1x64 and here are my results, run with my hardware.

Internet Explorer 9.0.8112.16421 220ms
Internet Explorer 10 platform preview 2.10.1008.16421) 234ms
Firefox 11 beta 250ms
Opera 11.61 (build 1250) 255ms
Safari 5.1 (7534.50) 257ms
Chrome 17.0.963.46 beta-m 277ms


As you can see, the results are very similar these days. So if you have an up-to-date browser, your fine.

And if someone is still using IE6 or 7, please upgrade a.s.a.p. check out the kill bill’s browser website if you are not convinced.

Enjoy your browser!
