It shouldn't be much more than twice as slow, because otherwise it would mean piraha would be slower than the old method. It would still be better than the old method, and it was never meant as a replacement for efficiency reasons, but it would be interesting to know what the difference is.

Do we expect Piraha to be faster than the old method?
