I dunno if it's just when the server upgrades it works faster at first... or not. I dunno if Mr. Darby enhanced performance in 1.1, but on my server after 5 seconds of using it.. I see the speed difference.
I just tried viewing MVC3Forum and CODForums [both are 1.0.4] just to compare, it takes a few more seconds to load just about everything. Page loads have sped up considerbly for me in 1.1
