@mpweiher@drewmccormack For evidence, you can look at what Apple does vs says. Are Mail, Aperture, Contacts sync, etc. all “corner cases”?

@mjtsai Not really. Some teams in Apple are surprisingly ignorant of Apple's own tech. What do they use instead? XML?
Rest my case.

@mjtsai It's always much faster operating on in-memory objects than on disk objects. In many cases it's a big perf win. - View other replies

@drewmccormack Aperture used to use Core Data, switched away from it, and got faster. -
