For some reason, this takes over a second to render 2 chunks, around 0.53 seconds to render a single chunk and almost a minute to render 100 chunks. Don't try adding decimals here as that will break the system, if you want decimal values you'll have to manually add it to the list 'AcceptedNumberValues'.
I managed to shave off 1 or 2 seconds by replacing the 2 blocks set x and set y with the 1 block set x and y
