I have IE 8, FF 3.6.8 and Chrome v6 all installed on my laptop. In a very unscientific approach (I did not actually time them with a stop watch) I am comparing IE 8 and Google Chrome. I have both set up to open 2 homepages and these forums when I first start my web browser (3 tabs in total). In my unscientific approach I could not discern any appreshible difference in the time for both IE 8 and Chrome v6 to open completely with all 3 web pages done loading. As I say this is not scientific because I do not have an accurate method to actual time these 2 events, but they sure seem almost the same. I do not see a difference at all. I do not see the faster loading that is claimed by Chrome. And since Chrome does have problems with certain web sites that I do use, IE 8 is my choice for now. I realize there is a Chrome 7 in development at this time.
FF actually seems slower than the other 2, again in these unscientific tests.
