Optimize Virtual Memory

About this task

Through the use of paging files, Windows allocates space on your hard drive for use as if it were actually memory. This space is known as virtual memory. This topic describes how to optimize the virtual memory on the Historian archiver computer.

Note: If the paging file is set to grow dynamically, your system may experience severe performance problems during runtime. To ensure optimal performance, the Initial Size and Maximum Size values for the paging file must be the same so that the paging file does not grow dynamically. For more information on creation and sizing of Windows paging files, refer to Microsoft Windows Help.

Procedure

Access Control Panel, and then select System > Advanced system settings > Advanced.
Under Performance, select Settings > Advanced.
Under Virtual Memory, select Change.
In the Initial size and Maximum sizefields, enter a value equal to three times your physical memory.
Select Set, and then select OK.
