Message interprocess communication has appeal for structuring operating systems but has the reputation of being slow. Register architectures have advantages for fast sequential execution but are considered to increase context-switching costs. This note describes an experiment in which registers are used for transmitting messages in the V kernel, resulting in a factor of 3 improvement in elapsed time for local message transactions and a factor of 6 reduction in kernel time for the associated kernel operations.
