[Zope] Object DB Capacity

[Craig Villamor]

We are currently in the process of building a site with Zope that we
anticipate will have a large object database. We have some concerns about
scalability as the database continues to grow.

What is the maximum capacity of the Zope object database? At what point
does performance begin to degrade?

Is it possible to have multiple Zope servers, each with a subset of
objects, working together to "load balance"? How about multiple object
databases on one zope installation? 

Any help would be appreciated.
