Database Performance Analyzer: What Are You Waiting For?

For most folks a database server is little more than a black box: queries go in, data comes out. But when the data comes out too slowly it falls upon you to take the lid off and make sense of what you find inside. In this presentation Thomas LaRock from SolarWinds will show you how the new SolarWinds Database Performance Analyzer (formerly Confio Ignite) uses response time analysis in the overall performance tuning process to help you understand what happens inside that black box.

- This is how most people interact with SQL Server. It is a black box, a virtual unknown. And most people that interact with SQL Server treat it about as well as (need a good analogy here). For most folks the idea of creating an email, or a word document, or a data warehouse is all the same: it’s just magic.

- We might as well be looking at the matrix. Look, I see a deadlock monitor, the query optimizer, the buffer pool, a blonde, a redhead, and the scheduler.
- Often what gets lost during those blamestorming performance tuning sessions is the fact that there are many layers involved when a system or application communicates with a database and then reports back information to the end user. This is where the idea of response time analysis comes into play. If you want to be an effective performance tuning expert then you should focus on analyzing the associated wait events at every step.
