SQL Server tries to optimize query performance itself, but its effectiveness in this may be influenced by several problems. The query optimizer of SQL Server is a component that is responsible for optimizing the execution plan of the query. Indexes and poorly designed queries can lead to unacceptable performance, no matter how well you design your database. Key issues related to query optimization include designing indexes, statistics, and index fragmentation. Key concerns in selecting an optimal execution plan are I/O processes needed and CPU resources required for query processing, and execution time required for query to return the results to the user.
