Maybe its just time for the entire FreeBSD team
to come out of its world of delusion and come to
terms with what every real-life user of FreeBSD
knows: In how ever many years of development,
there is still no good reason to use anything
other than FreeBSD 4.x except that 4.x doesn't
support a lot of newer harder. There is no
performance advantage in real world applications
with multiple processors, and the performance is
far worse with 1 processor.

The right thing to do is to port the SATA support
and new NIC support back to 4.x and support both.
4.x is far superior on a Uniprocessor system and
FreeBSD-5+ may be an entire re-write away from
ever being any good at MP. Come to terms with it,
PLEASE, because it is the case and saying
otherwise won't change it. 

My prediction is that a  year from now we'll all
be using DragonflyBSD and you guys will be
looking for a new bunch of beta-test guinea pigs.
