For me, the databases are small but nonetheless I want to keep them separate (and associated with each virtual site) regardless of whether they are being managed out of a single ZEO server or Zope instance. I would also like to keep this with a single ZEO if possible since a one to one ZEO server instance to zodb would not be so great on RAM resources of the server and in my opinion would be like using a cannon when you may only need a slingshot.
Regards,
David

I'm working on the scalability aspect of Zope, and am trying to see what the best practices are for creating multiple databases or multiple Zope instances. I am using ZEO and have allowed for multiple databases (Data.fs files) by editing zeo.conf just to try that out, because our current database is getting very large. The way I understand it, ZEO allows the work load to be distributed among multiple clients when you are getting a lot of hits, but does not address the issue of having a very large database for which it may slow down. So for this you would either create multiple instances of Zope/ZEO which each have their own database, or you would just create multiple databases within a single Zope/ZEO instance. Is there what is considered a best practice as far as choosing one of these options? Is there a database size I should try to maintain by distributing my Plone sites among different databases - or maybe just have a separate database for each? Or perhaps I am way off...
