My results with auto-refresh off are 4, 10.3, and 11.4 so about 4 times
faster than your machine.

   I'd expect a cheap current computer to be 2-3 times faster than mine and
a good current computer 5 or 6 times faster.

   I'd like to see a compromise between auto-refresh and no auto-refresh
with a refresh done every half second or 100 drawing operations so you could
see the developing picture but not cause the drawing to take much longer.
Had a quick look in the code but could not see how to do that.

   I used to be fascinated by this sort of thing when I was starting out.
