Question/Problem Description
How to rebuild any missing database table indexes in SQL Server to speedup database query execution?
How to rebuild database indexes manually?
Steps to Reproduce
Clarifying Information

A big problem is fragmented database space – resulting in slow inserts of new data in the database and also slow read times during page publishing. This is mostly due to the fact that Sitefinity is not using monotonically increasing primary keys, but GUIDs.

Error Message
Defect/Enhancement Number

CRUD operations in the database naturally cause SQL Server database tables to get fragmented.


The solution to this problem is the regular rebuilding of your database indexes. This is valid especially for the clustered primary key indexes which define the physical order of the database records.

We recommend rebuilding of the indexes with Fill factor lower than 100%, which will help so when a new record is inserted and needs to be put between existing records it does not cause fragmentation of the index.  If rebuild scripts are ran on regular basis and the application is not updated heavily with new data, use a fill factor of 90%. This should leave enough empty space on the database index pages for new records until the next rebuild, plus will not take too much empty space on the hard drive.

The rebuilding of the indexes must be executed when the site is not used, the database will become unresponsive while the indexes are rebuilt.

Preferably run the script during the night hours or weekends, depending on the business intensive hours. The rebuild times usually last less than 10 minutes, but depends on the database size. The index rebuild is atomic operation that is not considered a data corruption threat.

Below are two scripts to get statistic on fragmented indexes and to rebuild them.
