The windows page file stores temporary data for running programs and processes on your hard drive. The hard drive reads and writes are the slowest type of I/O on a computer so optimizing the hard drive reads and writes is important. If you have a second physical drive, moving the page file to this second physical disk that doesn't have the Windows Operating System can speed up your computer performance.

To move the page file, Right-click on My Computer -> select Properties -> the Advanced tab -> Performance, Settings button -> Advanced tab, Virtual memory, Change button -> choose the drives and size available for page file(s).


Even if you don't have a second physical drive, it can be worth it to set the page file to a constant size. Most experts recommend 1 to 2 times the amount of RAM you have. This will help keep the page file from becoming fragmented on the disk. If you don't have a lot of memory, you may want to avoid this step or set the page file size to be higher
