Thanks, reading that it says that native bignum support can speed things up. That's probably true - the only question is how much. If it's 25% vs 2,500% then that's what matters. I don't see an actual debate about numbers in that thread there, just generalities?
As I said above, I would expect JS to reach about half of the speed of C. It's possible that having native bignums would have removed some of that difference.
More importantly, the context here is PNaCl. Do you see a reason bignums could be emulated better in PNaCl vs JS? I assumed that's what you were implying, but perhaps I misunderstood you? Sorry if so.
