21 seconds to load my list page in Sydney, Australia in Firefox, with Firebug enabled. It seemed to spend a lot of time "waiting" when I looked at Firebug's Net tab.
Disabling Firebug helped a lot - it halved the load times in Firefox (~10 sec). It was faster in Chrome (~5 sec) and (GASP!) Internet Exploder 8 (~8-9 sec), all using Ctrl-F5. The load times for this "test" actually varied markedly, by 100% or so in all broswers. The Times I quoted here are the average of the faster times, +- my counting out loud margin for error.
I have a quadrillion extensions in Firefox so that is probably a factor.
