Abstract : The distributed V kernel is a message-oriented kernel that provides uniform local and network interprocess communication. It is primarily being used in an environment of diskless workstations connected by a high-speed local network to a set of file servers. The authors describe a performance evaluation of the kernel, with particular emphasis on the cost of network file access. Results show that over a local network: 1. Diskless workstations can access remote files with minimal performance penalty; and 2. The V message facility can be used to access remote files at comparable cost to any well-tuned specialized file access protocol. It is concluded that it is feasible to build a distributed system with all network communication using the V message facility even when most of the network nodes have no secondary storage.
