It did not take that long to be acceptable, I was mainly just running it as an extreme test, to ensure that there is nowhere in the code that starts misbehaving once you get into dealing with very large numbers.
As for whether it would render faster with another shading model or other geometry, that may be possible, but I suppose a similar effect could be produced by just restricting the number of bounces, too.
