If you have more than one physical disk, moving the page file to a fast drive that doesn’t contain your Windows system files is a good idea. Using multiple page files split over two or more physical disks is an even better idea, because your disk controller can process multiple requests to read or write data concurrently. Don’t make the mistake of creating two or more page files using multiple volumes on a single physical disk, however. If you have a single hard disk that contains C, D, and E volumes, for example, and you split the page file over two or more of these, you might actually make your computer run more slowly than before. In that configuration, the heads on the physical disk have to do more work, loading pages from different portions of the same disk sequentially, rather than loading data from a single contiguous region of the hard disk.
If you are short of hard disk space, you might consider setting a smaller initial page file size. You can use a handy script from Windows MVP Bill James to monitor current page file usage and session peak usage. This tool, a free download at
BillsWay.com, was written for Windows XP but works fine in Windows Vista. If this script nearly always shows current and peak usage levels well below the current page file size, you might want to consider reducing the initial size to save disk space. On the other hand, if you’re not short of disk space, there’s nothing to be gained from doing this and you might occasionally overload your custom settings, thereby degrading the performance of your system.
Should you enlarge your page file? Most users won’t need to do this. But you might want to keep an eye on the green line in the Memory graph of Resource Overview, as described above in "Ensuring that you have adequate RAM." If that line is spiking off the top of the graph a great deal of the time during your normal work, you might consider increasing the maximum size of your page file. (Disregard page file spikes and disk activity in general that takes place while you’re not actually working. This is likely to be the result of search indexing, defragmentation, or other background processes and does not indicate
