Performance Engineering Models of CORBA-based Distributed-Object Systems

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 for communication. 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, and illustrates with a case study.
