Yes

Undo on big prefabs with lots of overrides is very slow + eats a ton of memory (new in 4.3)

Editor - Other

-

1. open "scene"
2. disable the root Rocks_Explosion game object

On my machine this eats up 1.5GB of memory (can see in task manager) and takes 20 seconds the first time. Later enables/disables are faster (5s), but still take up tons of memory.
