1. Measuring SQL Server Performance
SQL Server Query Plan Analysis: The 5 Culprits That Cause 95% of Your Performance Headache
SQL Server is a great platform to get your database application up and running fast. The graphical interface of SQL Server Management Studio allows you to create tables, insert data, develop stored procedures, etc Initially your application runs great in your production, test and development environments, but as use of the application increases and the size of your database increases you may start to notice some performance degradation or worse yet, user complaints. This is where performance monitoring and tuning come into play. Usually the first signs of performance issues surface from user complaints.
In a course like this many different topics are discussed, so we start this training by briefly discussing the different topics and show how they relate to each other. In this module we see how SQL Server schedules queries to workers for running them on a thread. A very important concept is looking into wait statistics, where we basically learn to ask SQL Server what it's waiting upon. SQL Server stores its data on disk. In this module we discuss how data for regular data structures is stored, how the data can be spread over multiple disks and we discuss common performance pitfalls people encounter when they setup a SQL Server database.
