It doesn't work in this particular case because we are sending data that
cannot be cached (stock exchange prices and other financial information)
to a single client application over a network that is woefully
inadequate (so, yes, it's basically the LAN that is being saturated).
There are a number of fixes to this (like, oh, full-duplex) that are
simple, but we have fought that fight and corporate stupidity beat
technology.
