Towards a Framework for Reasoning about the Performance of Component Software

The issues concerning the performance of commercial-o#-the-shelf (COTS) components have gained much attention in the research community recently. Predicting the performance of a system constructed from components is beneficial for reasons such as bottleneck identification and performance tuning. However, the research status in this area is still relatively immature. Component technologies such as .NET and Enterprise JavaBeans o#er assembling platforms but do not provide any insights into the system performance before construction
