I think the test speed results are all highly dependent on the graphics 
card driver and CPU, so they will vary on different machines. OS X uses 
a much higher quality graphics rendering engine than OS 9, which is 
still using the very old QuickDraw. OS X is slower to draw in every 
respect, in any app.

You might be able to even out the speed difference by setting the "move" 
distances to 2 pixels apart in OS X. I don't think it will be visually 
noticeable and the move should only take half as long.
