    Hi all!

    I'm having problems with very long down time between making a script edit, and being able to interact with Unity again.

    The following test is after making a single edit to a single (non-editor) script. Profiling during this recompile/refresh reveals a few long frames, this one being most notable with 75s and 0.7GB allocations.

    I realise that this will not be instant, or even very quick, but I think that it should be doing it much quicker than around 80 seconds!

    Whilst it is compiling/refreshing, the progress bar is animating with the caption "AssetDatabase.Refresh" for most of the duration.

    About the project:
    Some of the code is in assembly defs, most of it not.
    Assets folder is 11.5GB.
    Unity Version: 2020.1.6f

    I have seen some people suggest a full reimport - I recently updated to 2020 from 2019 and it did what seemed to be a full import then. Maybe it wasn't a full one however, and if it's recommended I can reimport all tomorrow.

    Anyone got any tips to speed me up?

    Cheers,
    Andy

    Just wanted to chime in here a bit. I'm not seeing these extreme compile times, but I have a brand new project with no more than 5 custom scripts, and every change I make makes unity unresponsive for about 10 seconds. Is this normal? I have a few preview packages (hybrid renderer, entities, physics and UIToolkit) and TextMeshPro. Running an i9 MacBook pro from last year
