Abstract: Performance is the focus of crosscuts distributed real-time systems. Aspect-oriented technique is able to separate and modularize crosscutting concerns during the whole software development process, and therefore it is good for performance analysis. This paper proposes an Aspect-Oriented Performance Engineering Framework(AOPEF), which includes several AO-extended diagrams and normalized parameter specification, towards performance modeling and measurement of AO developed software. A distributed Web application paradigm is analyzed and the bottlenecks are found, demonstrating the feasibility and effectiveness of this framework.
