Linux's stack hasn't been rewritten from the BSD one, it was written
from scratch.

Linux's tcp/ip stack has been rewritten many times over the years
with the promise of large performance gains.

The fact of the matter is that the performance on the "bleeding
edge" of both systems, FreeBSD and Linux, is about the same.

>From a BSD proponent's perspective, I would take the pragmatic
viewpoint that everytime Linux reinvents its stack to get performance
or some other feature FreeBSD isn't far behind with a relatively
minor change to its stack to accomplish the same feat.
