-

Reproduction Steps:
1- Open the reproduction project (case_863912.zip).

3- Measure time taken by saving a scene.
3.1- Open Scenes/Transform/Transform_10000.unity scene.
3.2- Click on "Menu bar -> Test -> Test/Measure Save Current Scene". This will mark scene as dirty.
3.3- Save scene.
3.4- See the time taken by save operation in profiler.
4- Measure time taken by entering playmode.
4.1- Click on play button.
4.2- See the time taken by EnterPlaymode in profiler.
5- Repeat from step 3 with other scenes to test with different amount of game objects.

Expected Result: Entering playmode and saving scene scale linearly or close to linear.
Actual Result: Both operations scale exponentially.

  1. Resolution Note:

    This particular case has been investigated thoroughly and we have decided, in the interests of protecting the stability and features of Unity for users that rely upon the affected versions, to not address this fix for the time being. We understand that this will cause problems for some users, and so may address in a future version.
