Here's another idea: use Wireshark or a similar network traffic analyzer
to watch the traffic between browser and server.  Wireshark timestamps
every frame with a time in microseconds, so you can see where the delays
are (from the browser's viewpoint).

Wireshark used to be called Ethereal.  It comes with Fedora Core and if
it doesn't come with your distro it probably wouldn't be too hard to
add.
