title: canvas Performance of drawImage: many small images vs few large
body: <p>I was wondering if there are any benchmarks or clues about whether its better to draw one large image or call drawImage more often for fewer images. </p>
  
  <p>Example: </p>
  
  <p>I have a canvas of ~1600x1000 (when Fullscreen) and an Image that size. I draw this image onto my canvas each frame (hence I can save ctx.clearRect()). It has about 6 objects that I could easily draw each on its own in multiple drawImage-calls, but I'd need to do clearRect(); every frame.  </p>
  
  <p>Which is better in terms of performance? </p>
