SQL tuning is a fundamental process in any database that fixes problems in a deployed application. Before deployment, application designers set performance and security goals. When the SQL statement fails to meet those standards, it becomes a performance problem. A three-minute query may be too long for a user to wait for a response, or it may consume the CPU of the database host and prevent other queries from running. In either case, it is important to optimize the sqltuned.com statement in question to ensure that it is running as fast as possible.
Database Engine Tuning Advisor
When running an SQL tuning session, Database Engine Tuning Advisor can help you tune your data-driven applications to improve performance. The software has a variety of recommendations for tuning, including deleting existing PDS, indexed views, and partitioning. The recommendations are based on the current workload. You can select from online or offline recommendations to optimize your applications. After tuning your database, you can view and export your results to view the progress of your tuning session.
This tool comes with a user-friendly graphical user interface (GUI) that lets you specify your workload, select tuning options, and even tune a database. You can use the tool with SQL Server, or you can integrate it into your applications and scripts. This software can analyze any workload, including a Transact-SQL script, trace table, or plan cache. The GUI also lets you specify the Query Store workload for SQL Server 2016.
SQL Performance Analyzer
A report generated by the SQL Performance Analyzer from SQL TuneD compares the execution statistics and plan changes made to a specific SQL statement. This way, you can compare your current database performance to that of a prior test. It is even possible to compare the current and previous SQL statements, as long as you can get the same results in each test. The tool will also tell you how to improve your performance even further by optimizing your SQL workload.
Another great feature of the SQL Performance Analyzer is its ability to identify regressed SQL statements. Then, you can use the SQL Tuning Advisor to fix the affected statements. You can also use the database performance analyzer to determine the impact of changes to the SQL plan on the execution of a query. The results of the test will be presented in a detailed manner. Moreover, you will be able to determine the performance gain that you can expect once you implement the recommendations.
