* Speed: same between DEC Fortran & DEC Ada, Lahey Fortran and GNAT/DOS
for simple things. (pragma suppress_all -> =Fortran; else -> slower for debugging).
For big programs Ada is faster with a smart usage
of cross-package inlining (available with GNAT) and subtyping.
* Coding time, debugging time, human energy: you _can_ forget Fortran!
There are plenty of numerics resources there:

For finite elements, sparse matrices, etc. contact me for some sources.
