	All I can say is to follow the instructions I gave at the end, which are:

	The queryperf tool is one that ships in the contrib/ directory of 
the latest betas & release candidates for BIND 9.2.0, and creating 
the input test file would, of course, be specific to your particular 
network and what zone(s) your test nameserver is authoritative for.


	But my point here was that these systems were on the real 
Internet, and from at least one location, it seems that the 
BIND-based system performed much, much better.  It would be 
interesting to learn more about the hardware configurations of the 
two machines in question, as well as what OS and other software they 
are running, and retry the same tests against the same servers from a 
variety of places on the 'net.

	But I don't have enough accounts on different systems around the 
world to do that.  So, I can only test and post my results based on 
what is available to me.
