Memory\Transition Faults/sec

The Transition Faults counter returns the number of soft or transition faults during the sampling interval. Transition faults occur when a trimmed page on the Standby list is re-referenced. The page is then returned to the working set. It is important to note that the page was never saved to disk.

An upward trend is an indicator that there may be a developing memory shortage. High rates of transition faults on their own do not indicate a performance problem. However, if the Available Megabytes is at or near its minimum threshold value, usually 10 percent, then it indicates that the operating system has to work to maintain a pool of available pages.
