run time issues

Hello everybody. I am running some executables using a new machine where I installed a new version of silverfrost. I already have another machine with silverfrost installed and when I compile the same code and same options, the run time that the program takes is very quick (5 minutes). If I compile and run the program with the new machine the runtime become 45 minutes. The machines are running two different versions of Silverfrost. The fast one has an old Version that I haven't updated yet (7.10) while the slow one has the latest version. this are the options I'm using at the moment for compiling. Could you please help? thanks a lot!

Slow machine:

ftn95 $< /defint_kind 3 /deflog_kind 1 /no_com /ch /de /fu /im /mod_path \source\mods /cfpp /define DEBUG 1 $(ARGS) >>\compall.txt

quick machine:

ftn95 $< /defint_kind 3 /deflog_kind 1 /no_com /debug /full /c /im /mod_path \source\mods /cfpp /define DEBUG 1 $(ARGS) >>\compall.txt

To avoid confusion could you use the same form for the command line in the two cases otherwise we have to work out if /c is the same as /ch etc..

I changed the first command to the following .bat syntax

ftn95 /defint_kind 3 /deflog_kind 1 /no_com /ch /de /fu /im /cfpp /define DEBUG 1 %1 /lis >>compall.txt

( I basically removed the /mod_path option ) The resulting report was Silverfrost FTN95/Win32 Ver 8.10.0 insert_comma.f90 Tue May 23 21:21:21 2017

Compiler Options in Effect:
    CFPP CHECK COLOUR DEBUG DEFINE DEFINT_KIND 3 DEFLOG_KIND 1 DELETE_OBJ_ON_ERROR 
    ERROR_NUMBERS FULL_DEBUG IMPLICIT_NONE INTL LIST LOGL MINIMISE_REBUILD  NO_COMMENT 
    NO_QUIT NON_STANDARD SINGLE_THREADED 
 

I tried your second as:

ftn95 /defint_kind 3 /deflog_kind 1 /no_com /debug /full /c /im /cfpp /define DEBUG 1 %1 /lis >>compall.txt

The result was that /c started the FTN95 Local Configuration window with no compilation performed. You need to review the command you posted or the date stamp of the .obj file you are using on the new machine.

This was done with FTN95/Win32 Ver 8.10.0, but I suspect there would be little change with earlier versions.
