Den er strengt taget ikke nødvendigt hvis du aldrig kommer ud over mængden du har, men ved at beholde den øger du system stabiliteten. Anbefalingen, lad den være system managed.
Ikke de bedste argumenter fra MS, men derhen ad.
When large physical memory is installed, a page file might not be required to support the system commit charge during peak usage. For example, 64-bit versions of Windows and Windows Server support more physical memory (RAM) than 32-bit versions support. The available physical memory alone might be large enough.
However, the reason to configure the page file size hasn't changed. It has always been about supporting a system crash dump, if it's necessary, or extending the system commit limit, if it's necessary. For example, when a lot of physical memory is installed, a page file might not be required to back the system commit charge during peak usage. The available physical memory alone might be large enough to do this. However, a page file or a dedicated dump file might still be required to back a system crash dump.
