Have SharePoint Foundation spinning on a Windows Server 2012 R2.

VM is equipped with 4 CPUs and 20 GB of RAM.

It looks SharePoint is only using 25%, single CPU. Where to change this setting?

cpu stats

  • SharePoint is a set of very much running processes and services. Please look inside the VM and check TaskManager. Would be interesting to see, which process is limited to one CPU-Core. – MHeld May 11 '18 at 9:59

wsstracing.exe is the service responsible for SharePoint logging. Such a high CPU-Usage for logging-service is not normal.

Some things to check:

  • Go to SharePoint Central Administration -> Monitoring -> Configure diagnostic logging -> Check if any Categories are set to Verbose logging. Reset them to their defaults with the option Least critical event to report to the trace log
  • Restart the SharePoint Tracing Service (SPTracev4) in Windows Services Console (services.msc)
  • You might see the following errors in your ULS-Log: Trace Service encountered an unexpected exception when processing usage event. Detail exception message: Create store file error.. Win32 error code=5. This happens if the service account does not have proper permissions to logging-directory.

    • First get the correct user in services.msc: WSS Tracing Service-User
    • This account should be a member in the following local groups: WSS_ADMIN_WPG and WSS_WPG
      Tracing Groups

    • Get the ULS-Logging path in Central Administration -> Monitoring -> Configure diagnostic logging: ULS-Log Path

    • Check if permissions are correctly set on the logging folder. Both groups should have read, write and some special permissions: enter image description here
