Thanks Colin and Chuck for the insight.
Chuck, if you don't use WODisplayGroups at all, do you use a homegrown
batch navigator for big NSArrays?

I usually try to follow: build > profile > optimize
So the profiling step will tell me when I have to optimize the object
fetch.
I don't exclusively use WODisplayGroups, but I don't avoid them either
- whatever makes sense given the needs of the app. I use them for their
batching and sorting but rarely to manage the Object array, I prefer to
explicitly fetch for that.
I cannot vouch for them but you might want to check out one of the
fetch spec batch iterators or display group batch iterators that are
around. ProjectWONDER has them: ERXFetchSpecificationBatchIterator and
ERXBatchingDisplayGroup - I'm pretty sure there are others as well.
