Your server is going to be an authoritative server, a cache server, a mix
of both?

Because to test capacity, you should design separate battery test for each
function.

To test an authoritative server, you can query anything you like, because
I will give you a referal or an authoritative answer, without querying to
anyone else.

To test a cache server, you should create your battery test carefully,
because querying for too many "unexistant.whatthehell.key" will put your
numbers down. On the other hand, all your queries must not be "good
domains", because that will be an unrealistic test.

The tool to test a DNS server is queryperf, include in BIND 9 distribution.

The syntax is pretty straightforward and you specify the queries to be
sent in a "queries file".
