calidns [OPTIONS] QUERY_FILE DESTINATION INITIAL_QPS HITRATE
calidns reads queries from QUERY_FILE and sends them as a recursive query to DESTINATION (an IPv4 or IPv6 address, optionally with a port number), starting at INITIAL_QPS queries per second and aims to have a cache hitrate of HITRATE percent. It will then try to determine the maximum amount of queries per second the recursor can handle with the aforementioned HITRATE.
The format of the QUERY_FILE is very simple, it should contain "QNAME QTYPE" tuples, one per line. For example: powerdns.com A powerdns.com AAAA google.com A This is similar to Alexa top 1 million list.
--increment <NUM> On every subsequent run, multiply the number of queries per second by NUM. By default, this is 1.1. --want-recursion Set this flag to send queries with the Recursion Desired flag set.
