This gives timer.R, as well as results for
-- a quad G5 with 4GB RAM and R-devel compiled with vecLib and gcc-3.x
-- a quad MacPro with 5GB RAM and R-devel compiled with vecLib and
gcc-4.2.0
You'll see the MacPro/G5 time ratio is about 0.60, almost twice
as fast, for the hilbert and sort tasks. For loess the MacPro is
slower (!!),
but that probably is a function of the two different versions of vecLib.
I'll try the Intel compilers and the appropriate ATLAS (or Intel MKL/IPP
frameworks) later.
