Performance drops with Custom Editor

Hello,

I have a Custom Editor and as soon as I select the object in the inspector with this custom editor the performance goes slower. Am I doing something wrong or that I could improve on some way? Is a custom editor that much slower?

Thanks!

Code (CSharp):

I don't see any red flags.

Are there any errors in the console? Maybe it's not able to find one of the properties, and it's spamming the console.

Have you tried commenting out parts to narrow down the culprit?

 

Did you attach the Unity Profiler to measure what code is causing the performance issue? Might be easier to get told by the profiler what's slow, than trying to find it via guessing
