Such a table is pretty much worthless. A ZEO cache of 50.000 objects tells 
you nothing about the RAM to be used. The cache could hold 50.000 small 
objects or 50.000 very large objects eating all your RAM. The relation 
between #threads and hits also depends very much on your application.
To make it short: dealing with larger installation always requires some 
iterations of oberserving your system and tuning it.
