I wrote an application with a Fortran DLL that does numerical calculations for an Excel spreadsheet. I am concerned over its execution speed. I get fast execution on the development computer but it runs much slower when I move to another computer. The CPU utilitization is <10% for the second computer whereas it reaches 100% often for the development computer. What would slow down the second computer?
What files do I need to transfer to the second computer? I copied the following files:
model.dll (my new fortran DLL)
dforrt.dll (fortran run-time library)
model.xls (spreadsheet file)
The spreadsheet runs fast on a Fortran development computer on Win98 and another Fortran development computer on Win2000. The second computer that runs slow is Win2000 without Compaq Visual Fortran.
