Firefox 7 Official vs Firefox 9 Aurora vs Internet Explorer 9 vs Chrome

[Baalzamon]

With the recent release of Firefox 7, I figured I would do another analysis similar to my last involving Firefox 5, Firefox 7 Aurora, and IE 9.

First off, I'll post the previous results (These are the original results, not subsequent tests I have ran):

Browser/Test	Firefox 5	Firefox 7 Aurora	Internet Explorer 9
SunSpider 0.9.1 JavaScript Benchmark	362.6ms (+/- 1.6%)	342.1ms (+/-1.7%)	363.3ms (+/- 1.8%)
Futuremark Peacekeeper Rendering	3505	2785	4887
Futuremark Peacekeeper Social Networking	2721	4156	2295
Futuremark Peacekeeper Complex Graphics	11019	6743	10457
Futuremark Peacekeeper Data	5942	6671	9394
Futuremark Peacekeeper DOM Operations	2764	3946	2105
Futuremark Peacekeeper Text Parsing	5011	6186	8962
Futuremark Peacekeeper Overall	3792	4519	4567

Now for current results (Note that there is a new Futuremark test I am using that is supposed to be better):

Browser/Test	Firefox 7	Firefox 9 Aurora	Internet Explorer 9	Chrome

(Chrome to be added soon; May add Firefox 10 Nightly as well)

Given the tests I did between Firefox 5 and Firefox 7 Aurora, I'm not too worried about the fact that a majority of the things are actually lower in Firefox 9 Aurora than in Firefox 7, which is the current official version.

Thought I would mention that Firefox 8 doesn't have any huge changes.  Firefox 9's main goal is to increase Javascript performance.
