Databases used by SharePoint have fragmented indices (SharePoint Foundation 2010)

Applies to: SharePoint Foundation 2010

Rule Name:   Databases used by SharePoint have fragmented indices

Summary:   Microsoft SharePoint Server 2010 uses Microsoft SQL Server to store most of the content for the Web site and configuration settings. One or more of the databases used by SharePoint Server have fragmented indexes. A fragmented index can cause degradation in performance.

Cause:   Database indexes can fragment over time as a result of insert and update operations performed by SharePoint Server. We recommend that you periodically delete and rebuild these indexes to improve system performance.

Resolution:   Reorganize and rebuild indexes

1. To correct index fragmentation, you can reorganize an index or rebuild an index. For information, see Reorganizing and Rebuilding Indexes (https://go.microsoft.com/fwlink/p/?LinkID=160083&clcid=0x409).

Example: Index fragmentation with insert/updates, measuring it and fixing it
