The OP mentioned FFT but did not tell us whether he used FFTW with
Octave. That could make a difference depending on the code. Of
course, it is always pretty much impossible to say for sure why some
code might be slower or faster if you don't know exactly what the code
is. And it would also help to know what version of Octave (and
Matlab) we are talking about.
