SQL in the City 2016 presentation by Ben Emmett, Redgate Software.
It’s easy for simple mistakes in an application to ruin your SQL Server’s performance.
In this session, we’ll dig into some of the most common traps. We’ll look at overly chatty applications, and greedy or lazy code which prevents SQL Server doing its job efficiently. We’ll crack open the black box of ORMs like Entity Framework, exploring the performance challenges they present for developers and DBAs alike.
Finally, we’ll show how Redgate tools help you identify these problems, both in production and during development.
You’ll leave understanding the relationship between application and database performance issues, and how to proactively spot problems before they make it to production.
