AssetDatabase.Refresh takes significantly longer after each code change
How to reproduce:
1. Open the attached project (link in the Edit)
2. Make a change in any script and save
Expected results: AssetDatabase.Refresh takes under a second
Actual results: AssetDatabase.Refresh takes around 15s
Reproducible with: 2020.1.12f1, 2020.1.17f1, 2020.2.1f1, 2021.1.0b1
Couldn't test with: 2018.4.30f1, 2019.4.17f1 (Many many errors when downgrading, sometimes crashes)

This issue has been present in Unity 2020 and 2021.
2019 LTS is much much faster still.A 10 second "Hold On" is a thing of the past now. I'm lucky if it takes less than 20sec. And sometimes it's well over a minute. In a relatively empty test project I created a C# script and had to wait for more than 90 seconds for Unity to do something. That's all I did, just create a script and I couldn't do anything for a little over a minute and a half.
And all I ever get from support regarding this issue is "we're aware of it". For 2 years.... -

I can also confirm what Evan-Greenwood was experiencing

I have the exact same issue even on tiny projects. It seems to also be related to the startup time of the project where even the tiny ones are stuck on "Importing" for multiple minutes even when there is literally nothing to import.
this is seriously impacting workflows

Even on small projects I'm often told to "Hold On" now for 10 seconds or more when alt-tabbing back to Unity, or sometimes just clicking on something.
I've tested this in 2020.1.17 ... This wasn't an issue back in Unity 2019 (and my computer didn't get worse)

Resolution Note (2021.2.X):
This issue is being closed, and a number of smaller issues will be created.
This is due to the fact that AssetDatabase.Refresh kicks off a lot of systems, which, when initialized, end up taking time.
The following Unity specific areas were found to be able to benefit from additional optimizations:
Total time: 20s
Editor Compilation: 5.1s
Reload All User Assemblies: 3.9s
HDWizard Constructor: 716ms
WWiseSettings.LoadSettings: 322ms
AkWiseXMLWatcher: 131ms
Editor\Utils\VFXResources.cs OnEnable: 406ms
SetupComponentMenu: Doing multiple unnecessary file reads (335ms)
Editor\Models\VFXGraph.cs CheckCompilationVersion: 98ms
AmplifyShaderEditor.TemplatePostProcessor.PostProcessAllAssets -> Fix by upgrading to latest version
Issues for these will be created shortly.
