Every query triggers a database lookup, and the response from the database
is in text format, which has to be marshalled into DNS wire format.
This all adds significant overhead to DLZ query processing, and is the
reason I don't recommend DLZ be used for high-traffic servers.  If you
need high throughput, use DLZ as a hidden master and have standard
BIND servers acting as slaves to answer queries.
