title: html5 canvas general performance tips
body: <p>I am developing a game for html5 canvas while mainly targeting mobile devices. The canvas is resized to the biggest available resolution, so that it almost makes a fullscreen game.</p>
  
  <p>On an ipad that would be a 1024x786 canvas; at a resolution like this I notice a significant drop in framerate. On smaller resolution like 480x320 on iphone the game runs smooth! I guess this is because the device is fillrate limited.</p>
  
  <p>Anyhow I would like to optimize as much as possible. I would be very grateful if you could post any general performance tips that you have for html5 canvas development.</p>
