My experience with this site is that generally everything comes up pretty quickly. What slows it down is the selection and then display of the banner ads at the bottom of the pages.
There doesn't seem to be a problem at work where I have a very fast connection, but at home or on the road where I have to rely on a modem, things can get bogged down a bit.
This is a problem that is not isolated to FT. I have noticed it with several other groups that either have a variable banner ad system (different banners every so often in the same space) or ones that need to access banners from another location.
