and i have few optimizing strategy which i employ for best performance --- and that would be
1.increasing virtual memory
2.setting windows for best performance
3.doing few regedits or call it registry hacks
Increasing virtual memory will actually degrade the performance of the system because when your system needs extra memory it pulls the memory from the permanent media i.e. Hard disk and that operation will always be slower. So its always good to have the high speed memory enough and keep the virtual memory to a bear minimum for optimal performance.
