Compile Times and AssetDatabase.refresh

I'm Profiling my compile times with the CompilationPipeline events, and the actual compile time is only about 1.6 seconds. However when I make a script change the total time from editor focus until the refresh is done is about 8 seconds (I'm on a Ryzen 3900x with 32GB RAM).

It looks like a good bit of that time is spent on AssetDatabase.Refresh. Is there anything I can do to speed this up? And are there any other processes that are happening before or after compilation that I can look into speeding up?

 

Is your project using AssetDatabase v1 or v2? You can see that under "Edit > Project Settings > Editor":

It's using version 2.

 

Linking to a related thread in case anyone is searching https://forum.unity.com/threads/assetdatabase-v2-refresh-significantly-slower-than-v1.802635/, seems that there’s an underlying issue, possibly related also to https://issuetracker.unity3d.com/is...tes-slower-when-compared-to-previous-versions?
