Umm, if he is using a hub setting the card to full-duplex will cause
horrible amounts of collisions.  They should be half duplex.

Make sure you set the media type rather than allowing auto-select (the
default).

In your rc.conf on the freeBSD box, you need, in the ifconfig_xl0 line,

media 100baseTX mediaopt full-duplex

and in the properties for your network card on win2k you also should make
sure it's set to
100mb and full duplex rather than auto detect. Although it IS connecting at
100mb, the
auto detect routines use TONS of bandwidth to check which transport they
should be using,
cutting the rate right down.

I did this with my 10Mbps cards, and the rate went from 150kbps to 7.5mbps.
