Thank you for your response. How does one determine if they have a
"reasonably-sized" ZEO cache? In our case we have about 260,000 objects in
the database with an ideal cache size of 10,000 objects. I have no idea
what our hit/miss ratio is or how to find that out. Any assistance would
be great!

Thanks again,
