Performance Tuning in 21 Demos
You’re a developer or DBA who wants to tune indexes and queries to make your application go faster. You don’t like learning by watching slides or reading white papers – you want to jump right into the code and see what happens. You’re the kind of person who loves watching YouTube videos that start with, “Hold my beer and watch this.”

In one demo-filled day with Brent Ozar, you’ll see SQL Server 2019 make questionable lifestyle choices. It will wildly underestimate the work required with a query, pick the wrong indexes, and jump off the roof into the pool while holding the TV – all in an effort to deliver the right query results. Brent will show you how to coach the database engine into better performance and less problems.


  • You should be comfortable writing queries, but not at all comfortable with making them go faster.
  • If you want to follow along on your own laptop, download the free Stack Overflow 2013 database
  • Some of the demos will only work on specific SQL Server versions, like 2019 or 2017 – we’ll note that where applicable

Your Progress So Far in This Class

This is driven by the mark-as-complete buttons in each module of the class. (Let’s be honest: you’re probably just going to mark them as complete because you’re that kind of student. I feel you.)
