Verifying page file operation

To verify that a page file is actively placed on an IO Accelerator, you can browse for hidden files at the drive root. For example, run the following command at a prompt:

dir c: /ah

In the output listing there should be a file called pagefile.sys. If no page file is present, recheck the page file configuration in the Virtual Memory dialog box to verify that page file support has been enabled on the queried IO Accelerator.

Virtual Memory performance

Using the IO Accelerator as the paging store can improve overall Virtual Memory system performance. Actual benefits will vary widely with the application virtual memory usage and with hardware platform and performance.
