Constructing performance model of JMS middleware platform

Middleware performance models are useful building blocks in the performance models of distributed software applications. We focus on performance models of messaging middleware implementing the Java Message Service standard, showing how certain system design properties -- including pipelined processing and message coalescing -- interact to create performance behavior that the existing models do not capture accurately. We construct a performance model of the ActiveMQ messaging middleware that addresses the outlined issues and discuss how the approach extends to other middleware implementations.
