[Zope] Reasonable maximum # of objects in ZODB?

[VanL]

Hello,

I am trying to convince my boss to go with a Zope-based solution for a 
web app.  I had heard that the ZODB scales to about 5 million objects 
(products and text files, mostly) with reasonable performance.  Is this 
right?  What are reasonable performance and size limits for the ZODB on 
single-proc intel server hardware?

Thanks,

VL
