Performance tuning is the methodology of systematically identifying bottlenecks in applications, and improving performance.
There are some places to start performance testing.
Performance for an application can be a problem on various dimensions: Operating system, deployment (such as virtualization or not), platform (such as web server, and frameworks used), database, and configuration settings. It is possible to tune each of the above dimensions in different ways and configurations.
However, in essence, performance tuning is fundamentally about proper planning. Also, performance tuning is an art. Most often we are pushed to explore new ways to do performance tuning and testing.
The 10-page whitepaper “Beginning SQL Server Performance Tuning” discusses performance tuning, and its process, and the top six SQL Server tools. It looks at a possible approach to performance troubleshooting. Start from essential tools to find a high-level problem area, and then dig deep into solving the problem.
The idea is to make the primary initial diagnosis, perform proper tests, and finally find what would be a proper solution to performance problems in our SQL Server database.
