When talking about performance, you are using debug = 0, right?
Your best course of action will always be to profile your app and
therefore *identify* what is slow rather than guess at the usual
suspects.
That said, if you have 68 models and they are all inter related (i.e.
you could if you want go from any model to any other model by
traversing associations) that means all 68 models will be loaded for
each page load. Using Persistent models, or modifying the way you're
using associations such that they aren't all inter-related would help
with that.
