    Counter_Name Average Minimum Maximum
    -----------------------------------------------------------------------------------------
    Memory: Pages/sec 10201777
    Memory: Available Bytes 209731344183275520258355200
    Physical Disk: % Disk time001411
    Physical Disk: Avg. Disk Queue Length 0042
    Processor: % Processor Time 5045
    System: Processor Queue Length 003
    SQL Server Buffer: Buffer Cache Hit Ratio 10094100
    SQL Server General: User Connections 10399105

    The above are the values captured through performance monitor. As per the statement given in this site that the Memory: Pages/Sec should be less than 20, but in this case it is 102. This is taken from the sql server production box(clustered) and there are no other applications running.

    Could anyone advice whether the Memory: Pages/Sec value is proper and also the rest?

    I have read this article already.

    In this article they mentioned that the pages/sec average should be below 20. There is no maintenance plan and no other applications running on this system.

    I have also checked the memory settings and the values are:
    Min - 0
    Max - 2147483647

    And still i dont understand why the average pages/sec is 102.

    Thanks,

    - When u see high page/sec better to plot it against line graph and see which duration of day it stays high, thne investigate from there on.

    -Hardware configurations on the server plays vital role also, if you can describe RAM,CPU ....

    What about PLE (Page Life Expectency)?
    What is the toal server and configured memory? what edition of sql you are on?
    Do you see any perfomance issues other than counter is high?

    As the anti-virus is installed on SQL you would expect to see jump in pages/sec and memory utilization in this case. I would suggest to take benchmarks by stopping Anti-virus in this case.
