Under what OS?
AFAIK the only thing one can do is to find a compiler that optimizes for
the P4, but I don't know of one, nor if it actually helps. As far as I am
aware under both Linux and Windows the binary versions of R are not
even optimized for an i686 (Pentium Pro/II/III), but I find that under
Windows (and VC++) using the optimizations for i686 makes only negligible
differences.
