Optimizing 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. Be sure 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 run time. To ensure optimal performance, be sure that the Initial Size and Maximum Size of the paging file are the same so that the paging file does not grow dynamically. For more information on creation and sizing of Windows paging files, refer to the Microsoft Windows Help.
