drawImage or draw manually?

[pillar]

Hello,

I need to optimize my code a little bit and I'm wondering how to do it.

I am making this game where I need to create this 9x9 grid. I can do it by Graphics drawLine or then by having an image and drawing it with drawImage. My question is, which way is faster and preferred?

Images are always faster - the drawLine/fillRect &c commands are very slow on some phones...

drawImage() will be faster but will consume more memory (for the Image obviously).

If the game is heavy on heap use then the extra memory consumption might mean that the garbage collector start kicking in all the time and that will put a dent in performance. But this will only happen in extreme cases.
