Since it's in C, it probably has an edge, but as I've mentioned to antirez a couple of times, I'd love to see someone take a crack at this in Erlang - this is exactly the kind of thing it was built for.
Apart from speed what I like of C for this kind of projects is the self-contain-ness and the fact that most developers that may help in the development are probably able to read/write C but not Erlang.
