SPEAKERS: Joel Goldstein (Responsive Systems Company)
This presentation addresses the approaches, values, thresholds, triggers, and relationships of performance data analysis. Performance monitoring, analysis, and tuning should be a pro- active and continuous process; however, this often gets neglected because people are too busy with other work, or they are not sure what data is really important and which data quickly shows that there are problems - when nobody is complaining. Some basic thresholds and data provide quick insights about problems both at the application level, and the system level. Charts and graphs illustrate the surprising CPU and dollar costs of sequential prefetch and IOs.
