Nothing that comes very obviously to mind. I suspect that the main factor is that there are no calls on user-defined functions and fewer changes of dynamic context; also one call on string-join() to concatenate a sequence of 5 strings is likely to be faster than 4 calls of concat() to concatenate two strings.
