Designers are often faced with the problem of choosing among different functionally-equivalent software architectures. This choice is driven by non-functional factors such as performance, reliability, and topological/economical constraints. Among these, performance is one of the most influential factors addressed.

It has been claimed often that it is important to analyze the functional and non-functional behavior of the system under development as early as possible in the software life cycle. Software Architectures represent the first system abstraction that allow the effective validation of these properties. As far as performance is concerned, software architectures offer a first dynamic model of the system which should permit the validation of the gross-grain software architectural decisions. In this talk, I discuss approaches in the area and present a method that allows the derivation of a performance evaluation model, based on a Queueing Network Model (QNM), from a software architecture formal specification modeled as a Labeled Transition System (LTS).
