Regression
Yes
Performance regression when saving or making changes to a Prefab with lots of GameObjects
Reproduction steps:
1. Open the project inside of "prefab_regression.zip"
2. Select "Prefab Test 10000 (insanely slow)" and open it in the Prefab Editor
3. Inside of the Prefab make any change to it, such as add a component to any of the GameObjects
Expected: Prefab changes save fast
Actual: Unity takes a while to save the changes
Reproduces on: 2018.3.0a10, 2018.3.7f1, 2019.1.0b5, 2019.2.0a6
Does not reproduce on: 2017.4.20f2, 2018.3.0a9
Note:
- First noticeable degradation to performance noticeable in 2018.3.0a6, although in 2018.3.0a10 it is way more significant

This happens to me also on 2018.3.12f1. Simple changes inside a prefab, like moving a gameobject inside it, or selecting another gameobject causes Unity to slow to a crawl.
