Running DOS command from Matlab using system()

I am running an execution file of a Fortran code in Matlab using system(). running the dos command in Matlab takes approximately twice longer than when you run it from the command prompt window (i.e. from DOS).
Is there any way that we can speed up the process running this file from Matlab.
Thanks

Odd...
Does it happen to produce a lot of output to the screen? If so then perhaps system() is getting bogged down in collecting that output, as the second output of system() can be the output of the executable. If that is what is happening, then if you do not need the output, redirect it to the null device in the system command. If I recall, in MS Windows, that would look like
system('ExecutableName > NUL:')

Actually, I redirect them to Nul using system('ExecutableName > NUL'), but still the DOS command prompt runs it faster.
