Most people use the GCC Fortran front-end. I think the main reason you get speed from Fortran is because it provides more hints to the compiler, but also because generations of PhD students have been optimising compilers for Fortran-specific performance gains.

People that care about Fortran performance use Intel, PGI, IBM compilers.

  Maybe, but most people who are using numpy are probably using their Linux distro's package for it (or the pip package) which means it's being compiled using GCC.

    Depends if they work on HPC environments or not.
