Performance Patterns: Automated Scenario Based ORB Performance Evaluation

The performance of CORBA (Common Object Request Broker Architecture) objects is greatly influenced by the application context and by the performance of the ORB endsystem, which consists of the middleware, the operating system and the underlying network. Application developers need to evaluate how candidate application object architectures will perform within heterogenous computing environments, but a lack of standard and user extendable performance benchmark suites exercising all aspects of the ORB endsystem under realistic application scenarios makes this difficult. This paper introduces the Performance Pattern Language and the Performance Measurement Object which address these problems by providing an automated script based framework within which extensive ORB endsystem performance benchmarks may be efficiently described and automatically executed.
