This question would probably be better asked on the cocoa-dev list.
But basically, you should stop drawing directly, and instead use
-setNeedsDisplay: to cause a redraw at the next available refresh
cycle. Otherwise you might (that is to say, you probably will) outpace
the 60Hz refresh limit imposed by Quartz, which will then throttle
your drawing as a penalty.
