Depends. I'm getting a maximum of 240 queries/s on my 600MHz notebook
(PDNS and OpenLDAP on the same machine) if I disable caching
Remember that you will never get the same speed with a database
backend as with an in-memory backend (bindbackend for example). The
trick is to use high values for cache-ttl and and the other -ttl
options to avoid lookups from the database.
