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.
