	Keep in mind that I've done ~1400 queries per second on an 
ancient Compaq Armada 4131T laptop with a real Pentium 133 processor 
and only 48MB of RAM, running FreeBSD 4.6.2-REL, and on a zone that I 
know to be much larger than the amount of available physical RAM 
remaining on the machine (.tv).  This was using "nsd".

	For this same zone, the best performance I've seen outside of 
nsd, was about 667 queries per second with Nominum ANS.

	See <http://www.shub-internet.org/brad/papers/dnscomparison/> for 
my DNS benchmarking work.  Note that there are no results in here for 
PowerDNS, because I was not able to get a sufficiently suitable 
environment ready in time.
