Actually there is limited room for improvement.  The 4.2BSD compiler is
considerably better than the original f77 in that respect.  Published
work (by Jack Dongarra at Argonne National Laboratory
[dongarra at anl-mcs]) shows about 25-30% slower runtimes for the 4.2BSD
compiler over the VMS 4.1 compiler, for dense linear algebra.  I've
also coded some sparse linear algebra (essentially Yalepack) in
assembly and found only 30-35% speed up.  Let's give credit where
credit is due!

              Cheers,
