Are there any metrics about how to set the ZODB 'cache-size' (or cache-size-bytes) option? We've been using '5000' (arbitrarily chosen) for our Zope 3.4-ish app servers. We have access to zc.z3monitor which can output the "number of objects in the object caches (combined)" and "number of non-ghost objects in the object caches (combined)".
But I don't know understand how to interpret those numbers and use them to make better settings.
Thanks,
