Wow, very cool! Two questions: 1) One of the things that used to be the case with NIFs is that they can interfere with the BEAM's famed pre-emptive scheduling.

Wow, very cool! Two questions: 1) One of the things that used to be the case with NIFs is that they can interfere with the BEAM's famed pre-emptive scheduling. Any chance that's what's going on here? ie: the NIF solution was fast because it's getting an unfair amount of CPU time, potentially leading to latency issues elsewhere in the app? I believe recently that was changed, though, and the BEAM can pre-empt NIFs? 2) Did you consider/benchmark a port solution before NIF? I think of those as a little safer, but with not as good of performance.
