performance problem in P4 2Ghz

Melih

Hi everone,

I have a problem about increasing the performance of FLUENT in Windows 2000 Professional.

I was running a job in Windows Celeron 1.7Ghz 512 KB ram (the system was Windows XP). The CPU time per time step was around 30 seconds. When I looked the task manager, I saw that FLUENT was using 100 per cent of CPU and RAM.

Then, I put the same job in a much faster computer(it was P4 2GHZ), but in another system Windows 2000 professional. What I saw was a nonsense, because the CPU time was almost the same(around 25 seconds)!!!!.When I looked the task manager, I found out the problem. In that case FLUENT was using 50 percent CPU and 300 KB RAM. No matter I tried, I could not increase the performance of FLUENT even 1 per cent (for example, I changed the prority of FLUENT above normal in the task manager). So, could you please give me some advise? Should I change the system back to XP, or is there a way to increase the CPU and RAM usage in Windows 2000?

Thanks in advance...Best regards...
