comment How to solve performance issues with this ArcPy code?
You say "I don't think the code needs to be more described, because everybody can see what I want to do here from the code itself." but I am going to be honest and say that without dissecting it in detail, you cutting it down some more, and/or you providing more in-code comments, I have not been able to discern its intent despite having taken quite a long look at it.

comment How can I use attribute indexes on an attribute table in ArcGIS?
I think the question you may be trying to ask is "Does attribute indexing speed up arcpy.da cursors?" If so, I suggest you change it to that before anyone attempts an answer. However, we really need you to get into the habit of telling us more background to your questions like the software and version, where the data is stored, etc.
