Why high latency?

It uses a PersistantMapping, and I don't know how good they are at large numbers 
of objects... I'll just ask on zodb-dev@zope.org...

As someone else suggested, SimpleUserFolder would be the way to go.
You could store your users as documents (DTML of ZPT) in a BTrreFolder without 
having to write any filesystem-based code...

If you don't mind writing FS-based code, just use SUF's subclassing technique to 
write a userfolder that stores its user objects in a BTree of some sort...
