[Zope] Speed of Zope sever

Hey all, I seem to recall reading something like this before, but it could have just been a dream. Anyway, is there a correlation between the size of the ZODB and its speed at which it serves files to be viewed via http? Granted, we have only been on our development box, so when we finish sites, we'll just export/import them to the production server, but is there some way to speed up Zope? I've scheduled a meeting with our sys admin to see if he knows something, but I wanted to pool this resource as well. Thanks in advance, Tommy Innovation: The Best Way To Predict The Future ...
