Operating System


Similar to Pages/sec except returns the number of read operations on the page file to resolve hard page faults.

If the Pages/sec amount is higher than 1000 this could indicate the server is running low on memory. Page Input/sec and Page Reads/sec are very similar counters, Input/sec is the total number of pages, and Reads/sec is the total number of disk reads to retrieve those pages.
