Running Windows 2008 Server SP2 x64 Enterprise. Users on this server, hosting a custom app, are complaining that it's slow at certain points during the day. I can see high pages/sec during this time. Indicates a memory issue, but the server has 32GB RAM installed. Anything else to help isolate the cause? CPU and available memory looks ok, so not sure why it's paging so much.

Have a look to this Microsoft article named "PerfMon: High Number of Pages / Sec Not Necessarily Low Memory".

Thanks for the link! The article says: "These high values may instead be caused by the an application sequentially reading a memory mapped file" Is this necessarily a bad thing? Also, what counters should I be checking to verify that the high pages/sec is actually caused by the behaviour above and not a memory issue? And what should their corresponding thresholds be?
