Editor becomes unresponsive and performance is continually degraded when selecting a Scriptable Object with a large dataset



How to reproduce:
1. Open the attached project ("ScriptableObjectLargeDataset")
2. Select "Assets/data.asset"

Expected results: Inspector displays the view of the asset immediately and editor performance is unaffected
Actual result: Editor becomes unresponsive, the inspector then displays but editor performance is degraded

Reproducible with: 2018.4.32f1, 2019.4.20f1, 2020.2.3f1, 2021.1.0b5, 2021.2.0a4

  1. Resolution Note:

    It's by design that the Editor is unresponsive when a Scriptable Object has a very large string. String requires lots of extra-processing. A byte array is blittable and therefore much faster. The recommendation would be to use a different ScriptableObject for storage than the one for editing.

    Oh, I've encountered this issue before, and it's quite frustrating! It's disappointing when you're working on a project and the editor becomes unresponsive like this. I appreciate it helps to know if there have been any improvements or not.

    I can't find the location which you've mentioned above "Assets/XFrame/TestScene/Scene" also I'm not getting the same result for HTTPS:// my effort is to keep going to waste please sort this out.
