Which is a rather porous argument, to say the least.

Morons: "We've proven that our car goes much faster than the
	competition's does when we have all 4 doors open, due to the
	superior wind-resistance characteristics of our door design."

Competition:	"Why in god's name would you want to optimize for that?
		 Who in their right mind would drive with all the doors open?"

Morons:	"You're just jealous.  Beat our open-door numbers or shut up."


Likewise, testing things like loopback vs actual transmission
performance or no-load machine response is just as silly as optimizing
for the corner case of driving with your doors open.  Who bloody
*cares* what the results of a meaningless benchmark are, and why would
you ever want to get "better numbers" in an area of trivial
measurement where the only real result is to look better on some
marketdroid's tally sheet, no doubt obfuscating the code in question
and perhaps even degrading performance for the cases your users
actually *do* care about.

Those tactics might sound good to Microsoft or (though I hope not)
Linux, but the fact that many people use FreeBSD in *real world*
situations where performance under extreme load (>1000 users) is
paramount means that optimizing for these scenarios counts for far
more than chasing some micro-benchmark, and this is what has led John
to focus on specific types of performance over others.  We wouldn't
have it any other way, and you tell me - which is better for us,
making thousands of simultaneous TCP/IP connections work properly or
shaving another microsecond off a meaningless latency benchmark?

I'll give you an hour to answer that question, and you may use a
calculator.
