It all depends.  For example, it depends on how often you need to do
this thing.  If you do it only very rarely, I would assume that the
savings of your time (seconds? minutes?) is more valuable than the
wasted milliseconds of CPU time.  But, your milage may vary, as they
say.  Perhaps your time is worthless, and CPU cycles are really
valuable.  Lots of people behave like this is so.  I fall into the
trap myself from time to time.
