In my experience, fgetc() is pretty fantastically slow because you have a function call for every byte (and, I gather, modern libc does thread locking for every fgetc). It's usually much faster to fread() into a buffer and then access the buffer. I don't know if that's appropriate (or matters) here, though.

Have fun,
