Regression

Yes

AssetDatabase.Refresh() executes slower when compared to previous versions

Asset - Database

-

How to reproduce:
1. Open the attached project("AssetImportPerformance")
2. Go to BugReport > Create 100 assets
3. Observe console

Expected result: AssetDatabase.Refresh takes around the same amount of time regardless of Unity versions
Actual result: AssetDatabase.Refresh takes more time than in previous versions

Reproducible with: 2019.3.0a1, 2019.3.0a11
Not reproducible with: 2017.4.30f1, 2018.4.5f1, 2019.1.12f1, 2019.2.0b10

Note:
- It seems to reproduce only on HDD hard drives. Storing project in SSD hard drive results in expected behaviour even in 2019.3.0a1 and above.

    I'm experiencing this issue in 2020.1.0f1 too - slows me down a lot. Will this bug be reopened or is there already a follow up ticket so that we can track the status of this issue?

    Also still having this issue in 2020.1.2f1 ... it's infuriating how this locks up the editor for such a long time. I'm almost tempted to just downgrade everything to an ancient version just to avoid this.

    Using version 2020.1 and having this issue. Importing anything or changing a script locks up Unity for a long time.

    How is this a duplicate? This hasn't been fixed in 2020.1!

    I find this kind of behaviour too, my custom importer for 3Dtiles files, importing one big file take 3 minutes with version 1, now with the new version it take 18 min
