Pages (MEMmemPagesPerSec)

Displays the number of hard page faults for the processor, and the value often determines whether or not your system needs more RAM.

The number of hard page faults is equal to the number of pages read from, or written to, disk to resolve memory references to pages that were not in memory at the time of the reference. The parameter's value is the sum of the MEMmemPagesInputPerSec and MEMmemPagesOutputPerSec parameters.

Recommendations

• MEMmemPagesPerSec consistently greater than 5: If the average value for this parameter over time (that is, enough time to represent average system use) is greater than five, you probably have a memory bottleneck, and you may want to install additional memory.
• MEMmemPagesPerSec consistently greater than 10 to 12: If MEMmemPagesPerSec is consistently greater than 10 (10 to 12 is reasonable, but may vary with disk hardware) and MEMmemPageFaultsPerSec is greater than MEMmemCacheFaultsPerSec, the system is paging too much and you should consider installing additional memory and increasing the size of the paging file system.

Thresholds for alarms and warnings

You should set appropriate Alarm and Warning values for your system based on the Baselining Overview topic.
