The performance is worse than I would expect with a correctly implemented Floyd-Steinberg algorithm, I'd expect it to rasterize well even with a 2 color palette (that's easier to get right than RGB).
I don't at all mean to diminish the work, it's more a hunch that it's under-performing. I was dicking around with dithering last year, and had similar problems initially.
