FreeBSD 4.x and OS-X tcp performance

[Mark Tinguely]

Thinking about the trace a little more, the Apple send buffer must be set
much lower (about 18-19KB ballpark) than the FreeBSD recieve buffer (56 KB).
If these settings were simular, the Apple machine should be providing
more data as the FreeBSD gives the window updates - this would give
the FreeBSD side more chances to give duplicate ACKs to recover quicker.

For related curiousities, would you tell me if the FreeBSD a Uniprocessor
or multiprocessor?
