I haven't been able to run tcpdump up till this point because the field
trail folks won't tell me when they're running the tests.  I haven't
been able to get any real-world data (yet), and after the recent
drubbing that Linux made, I may not get a chance because they're
chomping at the bit to replace the box now.

> .) You won't look at the code.

Wrong.  I've merged in bugfixes.  But, I don't have time to walk through
the entire TCP/IP stack trying to figure out what's changed between 3.X
and 4.X to see what's changed.

> .) You won't give good details.

I'm telling you all the details I have.  If I had better details, I'd
have given them.  I've not said anything up till this point because I
haven't had good details, but Greg's post reflected the same sort of
behavior I've been seeing, so I was simply agreeing with his unknown
friend.

You call it FUD, I call it real-world results.  I'm not the only one
who's seen these kinds of results.

It's not my problem, except because of my interest in making FreeBSD
look good.  Fighting for FreeBSD has created me more enemies than
friends here, so I'm not doing myself any favors continually try to
defend the numbers/results we're seeing.

If you want me to shutup and go into a corner, it might make you feel
better, but it certainly won't solve the real problem.
