The Performance Testing Checklist is a comprehensive list of actions that need to be taken in order to ensure that an application is performing at its optimal level. This list should be used as a guideline to ensure that all performance metrics are being monitored and optimized. The checklist includes items such as ensuring that code is optimized, that the application is scalable, that stress testing is conducted, and that any bottlenecks are identified and addressed. It is also important to monitor the application’s resource utilization and response time. The checklist should be used as a tool to ensure that the application is performing as expected, and that any issues are identified and dealt with before they become major problems.
