haberman's rule for publishing benchmarks: you don't get to claim that you're >2x faster than your already-highly-optimized competitor without explaining why.

haberman's rule for publishing benchmarks: you don't get to claim that you're >2x faster than your already-highly-optimized competitor without explaining why. If you don't know why, you need to figure out why. Without explaining why, I will assume that it's not an apples-to-apples comparison, or that you made a mistake in your benchmarking.
