BIND9 includes a tool called "queryperf" that can be used to generate DNS query workloads against a DNS server and characterize the results. You'll need to provide zone(s) and a list of queries to perform. It's not imported in our contrib tree, but can be found in the port. Robert N M Watson Computer Laboratory University of Cambridge
