Paging File Usage (PAGEpgUsagePercent)
Displays the percentage of the page file currently in use.
Recommendations
When PAGEpgUsagePercent > 90%--When the page file usage exceeds 90 percent, Windows increases the size of the page file dynamically. This causes two performance-degrading events:
- Server performance is impacted by the dynamic update.
- The increase in page file size occurs in non-contiguous file space. When the page file is initially created, the file is a single contiguous block of disk space that can be efficiently written and read. The paging file should be maintained to minimize the need to dynamically change the file.
To avoid these two events: When the page file system usage exceeds 80%, increase the page file size as part of your routine maintenance program in order to create contiguous file space allocation and avoid dynamic allocation.
When PAGEpgUsagePercent <= 20%--If the system has an extremely large page file and a large amount of memory and if only a small amount of the page file is used, then you can consider freeing the excess disk space by decreasing the size of the page file.
Consider adjusting these values to suit the needs of your system based on the information in the baselining overview.
