I am excited to be able to tell you about an all day seminar that I'll be putting on prior to the Dallas SQL Saturday #255. The seminar will be on November 1, 2013. It's called Query Performance Tuning in SQL Server. We're going to cover the topic from an understanding of the optimizer to collecting data using extended events to reading execution plans and then on to lots of standard problems and their solutions. If you sign up before September 21st you can get a substantial early-bird discount, so I'd jump on it. Also, seats are limited, so don't wait too long. Let's get together and talk query tuning.
