Daniel,

Thank you for the suggestion to implement the definition of FFT
myself.  The way mathematica works behind the scene still remains a
mystery to me.  The 3D array was stored as a packed array in my
original code, so I expected that this would suppress any type
checking mathematica might do before processing and hence limit the
overhead.

Regards,

Peter
