"What is pages/sec performance counter ?"

The pages/sec performance counter is a memory related counter that measures the hard page faults. A hard page fault occurs when a memory page is not in the immediate memory and needs to be fetched from the disk. It is a very important counter that can potentially help us find bottlenecks. From my experience, a good warning threshold value for the pages/sec counter would be 10 and critical threshold value would be 20.

"What is page faults/sec performance counter ?"

The page faults/sec performance counter is also a memory related counter that measures the hard page faults and the soft page faults. A soft page faults occurs when the page is located in the immediate memory but still needs to fetch it for the current process. For example, Word has opened the spellchecker, and now Outlook wishes to use it, there is no need for another call to the disk as the spellchecker is already in memory. Zero is the optimum measurement and any mesurement higher then that delays the response time, however usually the value of the page faults/sec is at least twice the size of pages/sec.
