PERFORMANCES DILEMMA, computed properties in route or controller?

I’m using Ember 2.14.1.

Is it better that computed properties and something like that (until routeable components land) is on route or in a controller?

For performances reasons I mean. Is there any difference?

I don’t think there’s a different in terms of performance — it’d depend on exactly what you’re trying to do.

That being said, can you give a little more context? I think the answer will have to do with what needs to access that computed property rather than which is more performant.
