A framework for automated performance bottleneck detection

In this paper, we present the architecture design and implementation of a framework for automated performance bottleneck detection. The framework analyzes the time-spent distribution in the application and discovers the performance bottlenecks by using given bottleneck definitions. The user can query the application execution performance to identify performance problems. The design of the framework is flexible and extensible so it can be tailored based on the actual application execution environment and performance tuning requirement. To demonstrate the usefulness of the framework, we apply the framework on a practical DARPA application and show how it helps to identify performance bottlenecks. The framework helps to automate the performance tuning process and improve the user's productivity.
