Abstract

Systems using distributed object technology offer many advantages and their use is becoming widespread. Distributed object systems are typically developed without regard to the locations of objects in the network or the nature of the communication between them. However, this approach often leads to performance problems due to latency in accessing remote objects and excessive overhead due to inefficient communication mechanisms. Thus, it is important to provide support for early assessment of the performance characteristics of such systems. This paper presents extensions to the software performance engineering process and its associated models for assessing distributed object systems. These extensions are illustrated with a simple case study showing model solutions using the SPEED performance engineering tool.
