Hello,
I have run comparisons of a local build, MG's exe, and *B R14SP1 using the
benchmarks programs at:
http://www.sciviews.org/benchmark/
First, a note: This test uses a lot of looping, which tips the scales in
favor of "the real thing" - looping speed is one of the weaker points of
octave (But is rarely a problem in anything I actually do) . Any programs
sensibly written to avoid looping have comparable performance.
Second: neither Octave version uses ATLAS or MKL
Third: clearly the FFTW library is a worthy addition
My build was of the CVS image available on 12/1. Has something changed since
then that has caused a substantial slowdown in looping? Is there any reason
why a local build would have better optimization, even though the
compilers/runtime libs/build options are the same? (I think I followed the
the MSVC build instructions for msys, but who knows)
