If authoritative, it would be fascinating to know how many zones he 
has configured, and how large those zones are.

If recursive, it would be fascinating to know what he is querying 
for, and where the auth servers are located.

In both cases, knowing what he's using to generate the queries 
would be interesting knowledge.

Benchmarking is fun, because you really can get almost any number 
you want, as long as nobody's paying attention to your methodology.


PS: Small plug, if you are still using queryperf, please take a 
look at resperf and dnsperf. While not as useful in a 'get any 
number you want' way, they are much more useful in a 'get a 
meaningful number' way.
