Android Question IDE text editor is slow due to a few Warning #9?

I have about 15-20 warning #9 (Unused variable) in my code and it is causing the text editor to be very slow.
I can confirm that the editor is slow due to the Warning #9 because once I remove the unused variables or use #IgnoreWarnings: 9 , the editor is fast again.

(Note: Yes, I understand that it's good programming practice to not have many unused variables, or any at all, but I am copy/pasting old codes and the editor becomes too slow before I can finish using the variables)
