Nine Patch Image in Android Game

I am trying to use a nine patch image as a background in an android game. The image expands well in multiple resolutions but, my game has slowed down by 10 fps. I used to get a consistent 45 to 50 fps now I get 35 fps.

The question is when we use a nine patch as a drawable and set it as a background in a view does it have any performance implications as opposed to a plain bitmap drawing.

Thanks in advance.

If you are causing it to be stretched, then yes.
