Page Protection (PageFaults)

This parameter displays the number of detected page protection faults that caused pages to be copied. A page fault occurs when your system is attempting to execute a portion of a process that has been paged out of memory. Excessive page faults usually indicate a memory shortage. Occasional page faults are normal; however, because it takes longer to execute a process that has been partially paged out, excessive page faults degrade system performance.

Recommendations

The easiest (and often only) way to improve excessive page faults is to buy and install more memory. If you cannot add more memory immediately, you can schedule or terminate jobs with large memory requirements. You should become very familiar with your system's workload and standard processes. Killing frivolous processes and scheduling jobs with large memory requirements to run during non-peak times may improve performance greatly.

No range thresholds have been set by default. With the combination of your experience with your system, your system's workload, and your system's documentation, you can determine appropriate range thresholds.
