Fortran (unfortunately ?) is important to us; we've looked at Fortran execu-
tion times closely on our Sys III derivative, compared to BSD 4.2, Tops 20,
and VAX VMS.
The primary problems are most definitely in the math libraries. A loop such
as
DO .....
j = j+k
r = a*b
......
will stay within the 30% performance range mentioned previously. But insert
cos(), atan(), etc, and Unix Fortran slows to a crawl.
I/O isn't much better .................
