Unacceptable rendering response time (SharePoint Server 2010)

  • Article

 

Applies to: SharePoint Server 2010, SharePoint Foundation 2010

Alert Name:   Unacceptable response time

Event ID:   No event ID

Summary:   In typical Microsoft SharePoint Server 2010 deployments, pages should be rendered in less than a second to provide the best experience for users.

Symptoms:   One or more of the following symptoms might appear:

  • Response time to render content is consistently more than 1 second.

  • The Executing Time/Page Request performance counter exceeds its threshold.

Cause:   One or more of the following might be the cause:

  • A high volume of traffic that causes a high server load.

  • Slow network connections among servers in the SharePoint farm.

  • Poorly designed pages that contain a large number of Web Parts or a Web Part that sends a large number of server requests.

Resolution:   Diagnose specific pages that are rendered slowly

  1. If this is a performance issue for only specific pages in your sites, identify the page and diagnose the issue.

    1. Verify that the user account that is performing this procedure is a member of the Farm Administrators group.

    2. On the Central Administration the Home page, click Monitoring.

    3. On the Monitoring page, in the Reporting section, click View health reports.

    4. On the Review problems and solutions page, click Slowest pages, and then click Go.

    5. The pages that are being rendered the most slowly have the highest values in the average duration column.

    6. Contact the owner or developer of the page and request modifications needed for faster rendering.

Resolution:   Diagnose servers and network connections

  • If the performance issue is more general and affects many pages in a SharePoint farm, make sure that the servers in your SharePoint farm are located either on the same network or on networks that have high bandwidth and low latency connections.

Resolution:   Diagnose server hardware and software configuration

  1. Use Windows Task Manager and the resource monitor tools to inspect the hardware performance of the servers in your SharePoint farm.

  2. If the CPU usage of the servers is consistently high, consider adding hardware to reduce the load on individual servers.

  3. If disk usage on the servers is high or memory consumption is high, consider adding more memory to the servers in your SharePoint farm.

  4. Click OK.
