There ya go.  Accessed the site and it renders pretty fast on cable.
Considering the latency of a 56k modem is about 250ms, I would say it might
have problems at times.  Any return trip time of 200ms or less is ok for
your average page.

Moe's site seems to render ok too.  Got to be some dynamic that is not
apparent.

Given the complexity of Moe's site, I would be more than happy with it's
performance.  I even pulled up some of the PDF's and they seemed to render
ok.
