Microsoft SQL server tuning tips


1. Use the SQL Server Index Tuning Wizard: The Index Tuning Wizard is a tool that helps optimize query performance by suggesting indexes that you can create to improve the performance of your queries. 2. Use Query Store and Query Performance Insights: Query Store and Query Performance Insights are two new features of SQL Server that allow you to quickly identify and troubleshoot query performance issues. 3. Use good naming conventions: Use good naming conventions for your tables and columns to make it easier to read and understand your queries. 4. Ensure your query is using the right indexes: Make sure your query is using the right indexes to improve query performance. 5. Use query hints to override query optimization: Query hints are a way to override the query optimization process and force SQL Server to use a specific index or join type. 6. Use stored procedures instead of ad-hoc queries: Stored procedures can improve query performance by caching the query plan and reducing the amount of time it takes for the query to execute. 7. Monitor and troubleshoot long-running queries: Monitor long-running queries and troubleshoot them to improve performance. 8. Optimize your server hardware: Make sure your server hardware is optimized for the type of queries you are running. 9. Monitor and tune blocking: Monitor and tune blocking to prevent queries from being blocked. 10. Use the latest version of SQL Server: Always make sure you are running the latest version of SQL Server to take advantage of the latest performance enhancements.
