hmm.. don't switches route the appropriate packet to the switch port?
while switches dont route on IP addresses they still have to build a
table of MAC addresses to switchports. latency will appear if oodles of
busy machines are on the switch and depending on type of switching;
store and forward, cut-through, etc... it's true that the collision
light on the repeater/hub will produce sun-burn from the LED if oodles
of busy machines are speaking all at the same time. in theory there
would be very little collisions on a one-way transmission to one other
host on that same hub, but i don't want start that argument as that can
start a flame war pretty quickly ;-).
then again for light to somewhat busy home usage would moot my point as
transfer rates would be painfully fast and unnoticeable latency.

agreed. if the user wants to better his LAN performance then a full
duplex scheme would rule. getting a 100meg switch that does not support
full duplex would be kind of defeating the purpose. if price is an
issue, i havent seen a cheapo 100 meg switch that included full duplex
that's in the price range of a combo router/hub from Linksys, NetGear,
etc... or maybe i've been brainwashed by Cisco prices too long :-).
