Performance differences

[Intel_C_Intel]

Hello,
we discovered tremendous performance differences running the same non-optimised Fortran 90 code under NT4.0 and Win98. It does not matter where the code is compiled. The code runs much slower on Win98 machines (AMD Athlon 600MHz) than on NT4.0 machines (Intel PIII 500MHz).
What is the reason? And how can we solve the problem?
Thanks in advance,
Seb.

Without being able to analyze your specific application, it's impossible to know what accounts for the difference. Windows 98 is, though, slower than Windows NT. Also, the amount of physical memory you have can make a big difference for some applications.

Did you know that if you upgrade to CVF 6.5, you'll be able to compile with optimizations for the Athlon and Pentium III that will provide significant performance gains for many applications?
