Good move -- measuring is a good idea.

And yes: at the end of the days everything is just a call to the C-level R
API which supplies the values one at a time.  "Sugar" just hides some loops,
and unrolls (some) longer loops for speed.  It's easier to read and maintain
(we think) but not automagically faster.
