Although a number of commercial middleware products provide inter -operability in a heterogeneous distributed environment most of them sacrifice system performance. This paper summarizes the research on high performance CORBA compliant ORB that is underway at Carleton University. A number of approaches for achieving high system performance are investigated: using innovative client-middleware-server interaction architectures and exploiting limited heterogeneity in systems. Preliminary results of research on each of these topics are described.
