I'm not quite sure I understand how the shootout statistics work, and it's a bit  puerile to game benchmarks, but you can make nbody about 9% faster by using numeric rather than string indexes for the planet data.  Unfortunately, I think that to make a difference you'd need to get it under the median, maybe requiring a 30% improvement.
