    Hi. I found that latest Unity (2021.1.17f1) sometimes takes very long processing time when modifying assets.

    With 2021.1.15f1, modifying prefab or copying material is blazing fast (>1s), but with 2021.1.17f1 it takes over 30s.

    Here is the screenshot of deep profiling result when I copying material by pressing CTRL+D:
