As an aside, we find management of ZEO clients much easier if each ZEO
client of a particular system shares the same products and external
methods via an NFS share. That way we can untar one product and
push it
out to all of the clients simultaneously.
I'd be a little afraid of creating a sin

It can hold 16 billion billion pointers, with each pointer being 48
bits, thats 96 exabytes (100 million terabytes). Just for the index.
:) As an absolute minimum. Indexes normally being btrees

Well, the question was actually "What is the maximum size of this
file and/or maximum object ID? => just how many objects can the zodb
hold?". There is only a theoretical limit that has to do with the
largest index key for the ZODB i

No one has come against a "limit" yet as far as I know. Hitting RAM

ZODB size
What is the maximum size of this file and/or maximum object ID?
=> just how many objects can the zodb hold? millions? tens of
millions..?? billions...??? I have a feeling we'll run out of ram
long before actually hitting the limit but it'd be nice to know the
theoretical top limit.

Hi everyone, I've got a question I'd really appreciate some input on.
If I'm running perhaps a dozen Zope sites, experiencing anywhere
between several hits per second to a lot less, would it potentially
be more efficient (decreased latency etc.) to run each site as its own
