High CPU Usage (w3wp.exe) SharePoint 2013 Sites


  • We have installed Visual Studio 2013 in SharePoint 2013 development Server and restarted the server. Now we experience slowness to load the SharePoint web site.

    1. Reset the IIS
    2. Recycle the Application Pool

    I tried to open some list URLS and returns the error "An unexpected error has occurred."

    try open the site in SharePoint Designer 2013 and it's failed.

    Any hope to resolve the issue.

  • Hi Joy,

    Please add the system config details such as RAM, HDD capacity etc. and number of users connecting to the server simutaneously.

    I will suggest to check the users connected to the server in Task Manager. If there are too many disconnected sessions, contact the users and ask them to log off if they are done with the task.

    If there are too many users connected, then there can be the issue if the system RAM is limited.

    So let us know system details to analyze.

  • Are you running slq server in-place or stand alone? 

    If in-place you need to reduce the memory consumption SQL users and you will notice a significant change

  • Hi Joy,

    Thanks for posting your issue, I would suggest you to stop the Distribution cache service in SharePoint 2013 to load the pages fast. It might stuck in some cases.

    Also, Kindly go through the below URL for more details

    I hope this is helpful to you, mark it as Helpful. If this works, Please mark it as Answered.

  • Define the problem. All of the other three posts could be relevant but may not be.

    Do the sites take a long time to load the first time you open them after a reboot or sporadically? Do they then get much quicker?

    Do some sites load faster than others?

    Can you get in with SPD now?

    Do you have any errors in the event log?

    It isn't going to be user load, not if you've got visual studio installed on the server (and if you do on a production server you deserve everything you get). It might be RAM but the last time that is a bottleneck is straight after a reboot. Distributed cache will not have that sort of affect where you time out no matter how broken it is.

  • The issue is solved.

    Re-run the SharePoint configuration wizard, once the configuration is complete I restarted the SharePoint Server and everything is OK.

    Thanks all
