I got pretty much the same results on both browsers, 6.8seconds on Internet Explorer 8 and 6.9seconds on Firefox 3.5. So clearly, there isn't a big difference.
Well, if you wipe the cache on both and measure the load time, then that's pretty much what you can expect (seeing as the server responses are the bottleneck here). Try to load some long files from HDD and see what happens, for example: http://www.whatwg.org/specs/web-apps/current-work/
