saving almost empty scene takes ages

Unity Engine

Hello,

I have a problem, when I save my scene, it takes ages. Whereas the scene isn’t very big.
Like less than 2000 GameObjects for sure.

I tried to profile editor and it indicates that all the time is taken by a function : Write asset changes to disk.
I wonder why this takes so long. I was in depp profile but it didn’t gave me more infos.

have you any idea ?

As you can see, almost empty scenes take more than 3min (took 7min in the end) to save.

Hi @ ,

Does this still happen? Can you repro this problem AND supply a native stack trace?
I put together a guide on how to do that here: Debugging Editor freezes and hangs [Windows Only]
If the editor is stuck a long time doing something, and there’s no good info from the profiler, the native stack trace could help us figure out if it is indeed a mutex or something else that’s taking a really long time.
