Well, I guess the question is, why do you need the path? If you can avoid making a path at all, then you won't see the speed hit. Making the path is heavy because it has to do I/O on the disk. you can also avoid the hit if you *have* to have a path by only creating paths for folders. Since every file inside a directory will have the same parent path when iterating it.

I'm using FSRefs to make a speedy directory enumerator. When I
"sampled" it with Shark I found, to my dismay, that the slowest part
was CFURLCreateFromFSRef(). Actually the slowest function was
FSRefMakePath() which CFURLCreateFromFSRef() uses. After googleing in
hopes of finding a faster way I was forced to stick with the slow
FSRefMakePath(). I say it is slow because in an enumeration test of
/Applications 22% of the time was spent in that function, which (IMHO)
is too long.

Preferably there is a way to get a CFStringRef or NSString but if I
have to use a URL I'll survive.

I apologize if this is the wrong place to ask this, but I don't know
of another awesome mailing list like this one. If you do, and this is
the wrong place for this question, please redirect me.
