Pages Paged Out (PagesOut)

This parameter displays the number of pages of memory paged out of physical memory to disk. MEMORY pages are paged out when processes running on the system require more physical memory than is available. Occasional paging is normal; however, frequent paging degrades system performance.

Recommendations

The easiest (and often only) way to improve excessive paging 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.

The default range thresholds (Warning at 10 to 15 pages and Alarm at 15 to 100 pages) may be useful for the "average" system. However, systems with large amounts of memory may tolerate more paging than the average system, and systems with small amounts of memory may suffer with even light paging. By knowing your system's workload and characteristics, you can determine appropriate range thresholds.
