OK for a start your FreeBSD times are approximatly 1/3 the times
of the linux ones.. 0.3mS vs 1mS

secondly, pinging the loopback interface  doesn't test the ethernet
as the packet never goes anywhere NEAR the ethernet.

thirdly, if the ethernet is slow, and you haven't showed that it
is, you need to give your hardware configuration.
maybe FreeBSD is configured for the wrong interrupt..
that tends to make it slow..


lastly, 2.1 is way old.. you should install 2.1.5 becasue 2.1 is
hard to support as everyone has moved on.
