Performance Characterization Experience of Multi-Tier E-Business Systems Using Queuing Operational Analysis.

This paper describes the authors' experience of performance characterization of typical modern multi-tier e-business systems. The experiments are performed for both Microsoft* DNA and Java* server environments using commonly available measurement tools. Queuing operational analysis was applied in order to characterize system performance, scalability and bottlenecks. Close correlation of predictions with real measurements was observed. The technique allows quantitative comparison of different e-business middleware. Further, using this quantitative approach helps to provide insights into system behavior.
