The document discusses database performance optimization and management. It notes that performance issues often lead to finger pointing between teams. It then outlines the many demands on DBA time and how focusing only on reactive problem solving puts the business in constant reaction mode without understanding trends. The document advocates using a performance intelligence approach that focuses on wait time event analysis over traditional metrics. This approach collects wait time data in a repository to enable slicing and dicing the data similarly to business intelligence analysis. It provides context on other system activity. Senior DBAs can then interpret the data, identify bottlenecks, and make recommendations to optimize performance.
