Last time I posted on the latest browser from Microsoft vs. Mozilla's latest I had compared page download times between the two browsers. This time, I would like to take a brief look at how they stack up in regard to JavaScript.
John Resig (of jQuery / Mozilla fame) announced the Dromaeo: Javascript Performance Testing suite yesterday. The suite runs some of the same tests as the WebKit team's SunSpider, however, there are some improved methodolgies (see the suite's wiki for more info on this). I don't know how often I feel like doing DNA Sequence Alignment in JavaScript but I think it would be a good way to quickly get some metrics of how both FireFox and IE8 handle the code.
I ran the tests in groups because there were certain ones that were not finishing under IE8. To be quite honest, I'm not 100% sure if this is an Internet Explorer issue, or an issue with the tests. Both are a work in progress so I would rather not make assumptions at this point. Anyways, the results of the tests are listed below:
The initial results look like Firefox is performing the more advanced Javascript operations faster than Internet Explorer. That being said, Dromaeo, IE8 and Firefox 3.0b5 are still being developed so a lot could change before the release. For more metrics view a comparison on the Dromaeo site of Safari 3.1, Firefox 3.0b5, Opera 9.5 and IE8b1. Let me know what you think or if you've encountered different results.

Ayup. Its about what I expected. IE8's javascript engine is pretty sad compared to FF. Now compare IE8 to IE7! (this is fun)

There's a comparison of IE8 - IE7 (and 6) on the Dromaeo website http://dromaeo.com/?id=234,236,237 (the comma seperated list is part of the URL) IE8 is a lot better than the earlier versions but hopefully it's running in debug mode and that's why it's looking slow =P

Its pretty well understood that FF will beat IE8. Now do FF vs Safari and Opera..

IE used to be the fastest thing around. I remember early Mozilla builds were many times slower. Some of the developers couldn't figure out how IE did things so fast. It is amazing that Moz is faster now.

Encontre un problema con IE8, lo que sucede es que no ejecuta javascript, realice un reporte con Reporting Services (SQL 2005) y tengo un link ="javascript:history.go(-1)" que funciona bien en IE6, Firefox pero no funciona en IE8. Investigaré Saludos.
