Ah ha, that makes more sense.  It didn't occur to me that it would take
multiple roundtrips for a single GET.  Gee, now that I think about it, that
doesn't include the image gets either...

Why not? Sounds ok, setting up, using, and closing down a tcp line
should take at least 3 roundtrips, I think, so you'd need at least 300,
and if the data transfer takes a bit of time, bit of tcp stack overhead,
bit of software doing stuff... sounds like 700 ms.

running tcpdump might tell you exactly whats going on, with pretty
accurate timestamps.
