As a point of reference, we use a Discrete (Slow) Fourier transform program
a lot.  The original was written in Fortran, carefully structured for speed
at the source code level.  Some time ago the original author decided to
learn C, and used the DFT as a way to do so.  He re-coded the program in C
that had a strong Fortran accent.  It ran 25% faster.  The Fortran:
Microsoft for the IBMPC.  C: Borland's C++.
