Are you saying that Zope's startup and shutdown time is affected by the size of the ZODB? Yep. Over small ZODB's you wont notice the effect until it gets large. I found it very annoying when doing a lot of work in python and so had two databases, one with a small amount of data and one with a

While that would work for the simple object case, I find the prospect of storing a bunch of BLOBs (for the image data of the Photos) in an RDBMS to be *most* un-appetizing. Storing them on the server's file-system seems in-elegant as well. Okey dokey, just a suggestion. I have heard people
