This correspondence compares the measured performance of pipes implemented by a pipe server process on top of the V message passing transport protocol versus the calculated performance of pipes implemented by an operating system kernel and supported by a dedicated protocol. We describe the implementation of pipes in the V-System and present measurements of their performance. We then calculate the performance of pipes when implemented in the kernel and supported by a dedicated protocol. The performance loss as a result of using the pipe server is shown to be about 8 percent for network pipes and about 25 percent for local pipes. Given these figures and given the fact that messages and not pipes are the principal means of interprocess communication in V, we conclude that it is quite practical to implement pipes by a process using message passing, thereby avoiding the need for additional kernel and protocol complexity.
