SQL Server performance tuning is the process of determining the cause of observed or reported SQL Server issues and implementing the necessary changes to optimize the performance of your SQL Server database, application, OS, and hardware. To do so, you will need to make updates to some or all of the following aspects of your SQL Server environment:
Performance tuning can be time-consuming, complex, and frustrating. One change or correction can result in repercussions and problems elsewhere. That’s why most data professionals turn to performance tuning tools.
Performance tuning helps solve the following issues, some of which can have severe repercussions:
The benefits of resolving these issues include:
Ready to start fine-tuning your SQL Server database environment?
Begin with regular and comprehensive performance monitoring. Your goal is to frequently and regularly evaluate the health of each database and the performance of your SQL Server systems, both physical and virtual. By assessing factors such as user activity and complaints, query execution, and response times, you can determine where improvements are needed.
In this four-part eBook, Microsoft MVP Kevin Kline takes you through the process of identifying and resolving SQL Server performance problems using native SQL Server tools.
After you identify problems, you need to do some detective work to align each problem with the queries, execution plans, tables, indexes, joins, SQL Server and OS settings, and hardware that correlate with the issue. Then, you need to evaluate the code or components to determine why they aren’t working correctly and how to repair or improve the issue without causing unintended consequences elsewhere in the database or server.
SQL Server includes some built-in monitoring and performance tuning tools. However, when you manage databases across many systems, these tools might not provide the advanced functionality you need to optimize your database environment.
When evaluating third-party monitoring and performance tuning tools, look for the following capabilities:
Finally, make sure you understand the potential overhead of any tool that you use. Some tools can create performance issues of their own.

Slow running queries make up their share of performance issues. Our fully integrated Plan Explorer makes the entire process of query tuning fast and easy.
SQL Server is part of a database system. Not every slow SQL Server performance issue is caused directly by SQL Server. See how your virtualized environment (VMware or Hyper-V) impacts SQL Server performance.
Slow SQL Server performance could be caused by a number of factors. Our database performance monitoring solution allows you to see across everything required to monitor, diagnose, and optimize SQL Server and resolve performance issues.
