run time

I just bought the Visual Fortran compiler 6.6.0 to replace my "old" powerstation Microsoft Fortran 4.0. To my surprise, the Exe code is executed slower by about 20%. How can it be?
I use FL32 /Ox by both compilers from Dos.

Have you tried df /optimize:5 /fast /assume:buffered_io ?

The FL32 command, by default, disables some optiimizations. The command line James suggests should work well.
