Heya:
I'm still pretty early in the profiling. I've been mostly working to get rid of external dependencies 'till now, but it is getting somewhat faster as I find and kill dumb code that's probably the result of the transliteration (not stupid assumptions in the original...language impedance mismatches do that to you EVERY TIME).
Something like JSPerf is a much better idea than what I've been doing. I'll add it to my TODO list.
The most recent code is ~5-6x faster than the original on the unit tests. Here's some truncated before/after. The headline numbers are 1.78s for the original vs. 0.325 for the refactored code. More to do, though:

I found some more useless allocations/iteration. It's 8x faster now.
