Well, a full duplex hub is typically called a switch.  Just because the NICs
are at 100 Full doesn't mean anything.  Many times devices can be set for
auto negotiate and not configure properly.  You can force a setting on a NIC
and even if it wrong, it will still work, but there may be errors and
retransmissions will occur.  If you only have two devices in this hub and
they are only talking to each other, there may not be any collisions.
