I'm trying to scope out Zope 3's capacities.  Does anyone have a large
ZODB? How big is it (in terms of objects)?  Any performance issues?
Does anyone have a very high volume site?  What kind of volume with what
kind of degree of application logic?

What architectural things have affected performance?   I general we're
looking at using an RDBMS, but we're trying to get a better feeling of
when we can use the ZODB and when we should stick to the RDBMS. I like
the ZODB because of it's versioning information in particular.

We have various datasets:

1.      Transactions: 10-100 billion objects

per day, month, yr?

2.      Users: 10-100 million objects

up to 1-2 million objects seem to be common for large sites nowadays

3.      Contacts: 100,000 objects
4.      Customers: 100-1000 objects

Possibly you might consider a hybrid solution using the ZODB and a RDBMS.
