Every IDL distribution includes a copy of time_test.pro, which is
exactly the standard test suite you refer to. I've run this on quite
a few different machines, but I don't have the data here right now
in my home office. However, I do recall that my 90MHz Pentium system
fares somewhat better than a a SUN SPARCstation-10 on this test. I
was a little surprised by that result, so I used one of my own
Fortran FFT routines to compare my Pentium with the SPARC-10 and
got pretty much the same result. The Pentium is indeed impressive.
