With an average cache-object size of 13 KB (thats in the faq somewhere I
think) you will have 2016492 objects in the cache each using 72 bytes of
metadata using approx 138 MB for metadata only. Add to that the memory
cache size and metdata for that and the size of other data and the code and
of course other running processes and system memory requirements.

Hope this helps.
