Let's think about this logically people.. We're only talking about a MAX
of 187 Kilo-Bytes per second for a single T1 line... I've got calculators
that could max that out! Now.. When you start throwing multiple ethernet
devices in there, and you want to provide wire-to-wire speed acrossed those,
that is another story.. We're using a 486DX4-120Mhz w/32MB of RAM here, and
it is running 3 100Mb Intel Etherexpress cards, and 2 10Mb SMC Elite Ultra
cards.. It does a decent job, although I don't know that I would expect to
be able to get full wire speeds on all ethernet cards simultaneously.. But
luckily, we have enough segments and switches that we don't need to worry
about that, yet.
