When looking for information to help with performance tuning in SQL Server, Top SQL captures all of your worst performing and high-impact stored procedures, statements, and batches. Performance Monitoring and Tuning Tools Automatic tuning in Azure SQL Database also creates necessary indexes and drops unused indexes. Automatic tuning is enabled using the following command: Once you enable this option, the Database Engine will automatically force any recommendation where the estimated CPU gain is higher than 10 seconds, or the number of errors in the new plan is higher than the number of errors in the recommended plan, and verify that the forced plan is better than the current one. If the SQL Server instance is restarted before a plan forcing action is verified, that plan will be automatically unforced.
