--- Comment #3 from Thomas Koenig <tkoenig at gcc dot gnu.org> ---
I think I have an idea what might be the problem.

Does the code do something like

    call foo(a)

...

    subroutine foo(a)
      real, dimension(:) :: a
      call bar(a,size(n))

...

    subroutine bar(a,n)
      real, dimension(n) :: a

?

What might be missing for good performance is the
check for contiguous memory when calling bar.
