nsd users - Dec 2010 - howto optimize cachesize ?

Hi,

I'm faced with the question if my unbound's cachesize is large enough.

The ideal size is reached, if unbound discards entries from the cache 
*only if* their ttl was expired.

Could anybody recommend a testplan, which values should be measured?

Thanks & Merry Christmas!

sorry,
looks like the wrong mailing-list but maybe some nsd-users will use unbound
too...
