Performing routine database maintenance such as reindexing is important for keeping your databases running at peak performance. When you use INSERT, UPDATE, and DELETE statements to modify table data, indexes can become fragmented.

As indexes become fragmented, you get inefficient data reads when accessing tables and slower database performance.   Read more...
