The answer to that very likely depends on how many nodes you have, what kind of indexes you have, and what kind of queries you're running.  In my experience, accessing nodes later in a large document using the structural index is much slower than accessing nodes earlier in the same document.  I demonstrated that for queries using the preceding and following axes here:
