Performance Implications of Enterprise Software Development Using J2ee

The performance of enterprise software is a very subjective and context sensitive part of a research open to countless interpretation. Today, more and more organization wants to have a distributed enterprise application for their day-to-day endeavors and leverage the speed, security, and reliability of server-side technology. As such, enterprise applications have to be designed, built, and produced for less money, with greater performance, and with fewer resources than ever before. It is very important for organizations and developers to realize the performance implications of enterprise system developed using the Java 2 Platform, Enterprise Edition (J2EE) which is the typical platform for hosting enterprise applications written in the Java programming language. This paper investigates how J2EE application model (design pattern) influences the performance of distributed systems. The presented case study of J2EE web application is used to determine if the J2EE application model can have a positive impact on overall enterprise application performance. In view of the fact that scalability is a major performance factor, how does the scalability affect latency and throughput? An experiment on which performance characteristic of the enterprise application design based on J2EE application model have a major impact on performance is performed. These experiments confirmed that the choice of design pattern or alternative can influence the overall performance of the application because the average response time, the success rate, the throughput, latency and the scalability are all swayed by the design pattern. Some recommendations and general guidelines that can help determine performance impact of J2EE solutions in distributed systems have been made.
