I just checked the number of entries in the hosts files at these two sites:

   http://www.hosts-file.net/
   http://www.mvps.org/winhelp2002/hosts.htm

The first one has about 57769 entries and the second has around 13980. 
It is likely there is a lot of overlap.  Since rbldns is designed to 
efficiently handle that many entries, it would have been nice to be able 
to use it.  It don't know how bind would do with that.

I have seen comments that djbdns is faster and more efficient than bind, 
so I think my next step is to try out djbdns.  At the present, I don't 
have time for running a performance comparison myself, so I am going off 
of others comments and testing that can be found around the net.  For 
example:
