you could put stuff in models and export those, delete the model and then import them again as a reference – now you can offload models to alleviate the scene while working. to a degree import/export as a model can do some clean up – and rebuilding your scene as a new scene with only reference models can make a huge difference.
if with layers you mean renderpasses – the objects in a model keep their assignment to partitions (test it first of course, it’s in one of the deltas, group memberships or so) – so the renderpasses should be good. dunno about layers, as I don’t use them, but it might also work – I guess it’s the same delta. something else entirely - you don’t have any icetrees (elsewhere in the scene) by any chance? I’ve found they can seriously slowdown interactivity and viewport refresh – even when invisible! something with checking their validity on each change of the scene.

Wouldn't be surprised if it contained some garbage already. How can I mop up? Merge? Means loosing all layers, right?
