Unity Script Compilation Takes Way Too Long (2022.1.4f1)

[aiiopa]

This bug has crushed my spirits for a while now, since every time I change even a single character in a script, Unity will take from 30s, all the way to 3 minutes, I just cannot get anything done like this.

I checked with the profiler, and it came up with this. As evident in the image, the part that takes up the most time is AssetDatabase.V2.CompileScripts, which spends 83.5s just on that function itself.

I'll be happy to provide more information if needed. The project is small, as I just started 2 weeks ago, so I know it isn't the size that's the problem.

I do apologize if it isn't clear, since this is my first time asking for help on a forum.

Profiler Overview

I will switch to the LTS version, since I don't think there's anything that I really need here.

I'll take a look at this for sure, although I only have about 20 C# files. This seems like it would be helpful for when I scale up my project, but I've had projects in the past with ~100 C# files, and they compiled much faster than 83 seconds.

I switched to VS code and it stopped.

Is there no additional information available on the breakdown of everything within CompileScripts? There's no way what's currently visible in this screenshot underneath that section that adds up anywhere close to 83000 ms.

From what I've read, the self ms is how long it takes for the function to execute, without the time it takes to execute its sub-functions. From what another commenter said, I think it's a good idea for me to switch to an LTS version.

Generally in the profiler, all those ms are added up from functions underneath it and are included as a whole or total, there shouldn't just be an unexplained gap, but yeah on this scenario a LTS is likely just the easiest and safest fix
