To determine the size of the pagefile, multiply the amount of physical RAM by 1.5. However, placing the pagefile on the boot partition does not optimize performance because Windows NT and Windows 2000 have to perform disk I/O on both the system directory and the pagefile. Therefore, it is recommended that you place the pagefile on a different partition and different physical hard disk drive so that Windows NT and Windows 2000 can handle multiple I/O requests more efficiently.
