Professional SQL Server® 2005 Performance Tuning

Book Description

Written by a team of expert SQL users, this comprehensive resource approaches performance tuning from a new perspective by showing you a methodical scientific approach to diagnose performance problems. The book first walks you through how to discover bottlenecks when something is wrong and you'll then learn how to identify and remove the problems that are causing poor performance. You'll discover preventive measures you can take to try to avoid a performance problem entirely and you'll learn how to achieve better performance.
