Thanks for the info.  I was hoping someone had stats on the number of
entries and memory usage.

Hi Matt,

You may simply use empirical dependence from cache entries to memory
I set max-cache-entries=2000000
and have approximately 500 ( +- 15 Mb, less than 1 percent )Mb of memory

usage on my recursor boxes.
