The 'segment' is the 'virtual piece of wire' formed when you plug that machine
+ others into the same hub (assuming it's not a fancy / expensive 'switching'
hub)... Only one machine can transmit or receive at a time on one 'segment'
(as it appears to be only 1 piece of wire per-se).

If you've got a lot of other machines on that 'segment' (read: Hub) - and
they're all fighting to send / receive data, 600k a second is pretty good
going...

If you really want to test it, either connect your FreeBSD machine to another
machine via a cross-over cable (not recomended) - or disconnect _all_ the
other machines except the 2 your using the test from the hub (or preferably
find another hub and just plug the FreeBSD machine + the other machines your
using for the test into it! :-)

Here I'm lucky to get 200k/sec to some of our machines because of local
congestion etc.
