Lahey Fortran and Core 2 duo

Interesting issue. I have access to two Dell Precision M4300 workstation laptops. On both machines I installed my copy of Lahey Fortran Pro 5.5 (LF9555). I also have an old Dell Dimension D8300 desktop with the compiler on it.

Even though the laptops are suppose to much, much quicker from all aspects (cpu, HDD, bus, memory, etc), a 6 dof simulation runs over 3 times slower on the "faster" laptops.

Are there any known issues with Lahey Fortran and Core 2 Duo (Santa Rosa) machines?

Thanks,
Harvey
