The page fi le is supposed to be on the disk that has the highest transfer rate in the PC. For example, if Windows has to move larger graphics and an older disk transfers data at only 10 MB per second, the computer comes de facto to a standstill. Determining Transfer Rates: To start with, download and install a free tool named HD Tune from ‘www.hdtune. com’. Select the desired hard disk in the upper part of the window and activate the ‘Benchmark’ tab in it. Click ‘Start’ and wait for the analysis to complete without using the computer during this period. Now note down the ‘Average’ values in the ‘Transfer Rate’ and ‘Access Time’ areas. Repeat this procedure for other internal drives. Moving the page fi le: For the page fi le, select the disk with the highest transfer rate and defragment it. After you have fi nished defragmenting the selected drive right click on ‘My Computer’ and click on properties. Click ‘Settings’ under ‘Performance’ in the ‘Advanced’ tab. Switch to the ‘Advanced’ tab here and click ‘Change’ under ‘Virtual Memory’. Select the drive you just determined to be the fastest and enable the ‘Custom Size’ option. Enter the same value in the ‘Initial Size’ and ‘Maximum Size’ fi elds in MB and click on 'Set'. Note: The page fi le should be double the size of the installed RAM, and if you have space to spare, keep a fi xed size for the page fi le. Now select the slower drive on which the paging fi le is currently saved. Select the ‘No Paging File’ option and click on ‘Set’. Finally, confi rm all the open dialogs with ‘OK’ and restart the computer for the changes to take effect
