Caching only DNS server

I have recently setup a caching only DNS server and it is working great. 
I am trying to find some info on the nature of the beast I have built. I 
gather that the cache is in memory only and is not saved to disk 
anywhere and is flushed at each restart. (Bummer.)

What I want to know is how this cache works. Is the size of the cache 
just limited my the amount of memory or are there some default 
limitations? If I put a bunch of memory in this box will it be able to 
have a huge cached database, provided the TTL is high enough? Is this 
even advisable?

Any thoughts, comment or suggestions would be appreciated.
