Experiences of using LQN and QPN tools for performance modeling of a J2EE Application

摘要

Performance of a J2EE application is influenced by the underlying infrastructure, operating system and middleware parameters. Usually a reactive approach of testing is used to configure these, which is costly and lengthy. Consequently a proactive approach of performance modeling is required. Layered Queuing Networks and Queuing Petri Nets are two such effective techniques for tuning environment. This paper articulates our experiences with these techniques for a J2EE application. The relative attributes of the two techniques are listed to provide an insight on their suitability in a context.
