Yes, queryperf is not suitable for RRL. Of course, I used it at first
test. However I was confused by the report of it.

Here is my testing procedure.

1. setup the BIND *without* RRL
2. using 'queryperf' to that target
3. capture query data of 'queryperf' with 'tcpdump'
4. stop the BIND, then start the BIND with RRL
5. replay query data with 'tcpreplay' and test it
