With respect to the argument order reversal changing the run times, there are
various hacks in the memory sub-system designed to improve sequential  memory
access.   This  includes  read-ahead.   Thus, other things being equal, it is
better to do things in increasing address order.  Of course it could just  be
luck having to do with cache line alignment.
