Well, FreeBSD TCP performance sucks or it does some things which can
make it suck badly.

>From simple observations (hub leds, ftp's meter), ftp'ing from a laptop
(3c589d) running 2.2.6 to SunOS4 (LX) is considerably worse than in the
other direction.  Although I do suspect the 3c589d (or its driver - zp ?)
do not handle ethernet collisions at all in a good way to be a possible
cause.  I've never known ethernet ftp performance so bad as with the
equipment just mentioned.
