of course, there is encryption overhead involved in doing any secure ftp.  
do you notice any collisions?  are you doing the same type of transfer
from w2k to w2k as you are from w2k to freebsd?  can you give us some
numbers to compare with, its difficult to understand what you mean by
"slow".  changing the card in freebsd to do FD should have made a huge 
difference.  please provide some more info.  thanks
