I'm a bit amazed I've received downvotes for this post. I'm saying (1) you don't know how much this will speed up by going to C without trying it and (2) you don't know how much of the speed up in this case comes from the OP having written it in C and how much comes from the fact that it's a different algorithm. The fact that anyone would disagree with these (obviously true) statements is kind of incredible to me.
