A system and a method for reducing the number of Object Request Broker (ORB) connections in an Internet Inter-ORB Protocol (IIOP) or similar distributed computing environment. The system reduces the total number of connections needed between the clients and the servers. Embodiments include an intelligent concentrator process for requests going from within a domain to outside of the domain. The concentrator can allow concentration by ensuring that multiple requests from within the domain use the same actual connection for their requests to an object implementation outside of the domain.
