Does disabling collisions save any processing power?

... if the object in question doesn't have any collision events to begin with?

I have a large layout with a bunch of background objects that are just going to sit around doing nothing. While fiddling with them I remembered there's a parameter to disable collisions, but, it's not like I'm checking for collisions to begin with. Is there any advantage to going through them all and disabling their collision detection?

Not really. It would only help if you were checking for collisions.

Using render cells under layer properties would probably save you more.

Alright, I figured as much. Thanks!
