Description

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.

1. Add additional memory
2. Adjust the Max memory allocation of SQL to remove OS pressure
3. Determine and address what application/services are impeding on SQL Servers memory allocation
4. Data page compression if CPU usage doesn’t suffer
