Page file performance monitoring

A paging file can be read as a connected chunk of data from RAM, which is must faster than reading the data from multiple locations. The Paging File Percent of Usage counter is useful to determine whether the paging file is the appropriate size for your storage and system operating needs. To determine your needs, monitor the counter as your computer performs under working conditions. Do this over a period of time to get a clear representation of how your paging file is performing.

Ideally, your paging file size should be 1. You can calculate your minimum paging file size with this equation: 8 GB x 1. If your paging file size is not sufficient for your needs, you can seek one of three solutions:. Add on to your memory. Increase your paging file size. Log in as a system administrator. Restart your computer. Operations that exceed the limited RAM space are automatically sent to the file to be stored if you have the paging file enabled.

Your paging file size should be 1. The system commit memory limit is the sum of physical memory and all page files combined. It represents the maximum system-committed memory also known as the "system commit charge" that the system can support. The system commit charge is the total committed or "promised" memory of all committed virtual memory in the system. If the system commit charge reaches the system commit limit, the system and processes might not get committed memory.

This condition can cause freezing, crashing, and other malfunctions. Therefore, make sure that you set the system commit limit high enough to support the system commit charge during peak usage. System-managed page files automatically grow up to three times the physical memory or 4 GB whichever is larger, but no more than one-eighth of the volume size when the system commit charge reaches 90 percent of the system commit limit.

This assumes that enough free disk space is available to accommodate the growth. Skip to main content. This browser is no longer supported. Download Microsoft Edge More info.
