Memory: Page Faults/sec counter to make sure that the disk activity is not caused by paging.Ī low rate of paging (and hence page faults) is typical, even if the computer has plenty of available memory. Pages/sec counter could indicate excessive paging. Low values for the Available Bytes counter can indicate that there is an overall shortage of memory on the computer or that an application is not releasing memory. Hard faults persecond free#Pages/sec counter indicates the number of pages that either were retrieved from disk due to hard page faults or written to disk to free space in the working set due to page faults.
