Considering the recent observations SFHQ and I have made I'd be tempted to
seriously get on board with this.
I'd like to see IE6 and IE8 javascript and image rendering performance compared on identical machines. Or the same machine. I suspect IE6 may blow IE8 out of the water. I wonder if I install IE8 on my XP install if I can roll it back to IE6? Probably not.
edit: ah wait, SFHQ had reported stats from IE7 not IE6. I did test IE6 performance recently and it was worse than SFHQ's reports on IE7. Surpisingly though, IE8 perfomance is inferior to IE7.
Love the comments on the site though.
