beginner's questions about fluent paralle processing

My computer has a core i7 920 (quad core) cpu, 12gb memory, and vista 64bit. Now I am using fluent 6.3 64bit to perform paralle computing. The grid info is as below:
Level Cells Faces Nodes Partitions
0 57756 121860 62462 1
The computation time for serial computing is about 9 h. The wall-clock time for 2-processer paralle computing is about 5.5 h. If I use more than 2 processors, the wall-clock time does not change. I am wondering if it is because the nodes are two few.
Plus, I noticed that when fluent was running the page file usage increased. Can I increase the usage of memory and reduce that of page files? I think that would make the computation faster.
Another question is that it is better to turn on SMT or not?
Thanks in advance.

Your mesh is too small.
Try with a mesh with 1 million cells you will see the difference
