Abstract :
Results of a study that attempts to characterize the performance of the SunOS Inter-Process Communication (IPC) and TCP/IP protocols for distributed high-bandwidth applications are presented. In general, it is found that the performance of SunOS 4.0.3 IPC on Sparcstation 1 over the Ethernet is very good. An experiment has shown that average throughput rates of up to 7.5 Mb/s are achievable. Further investigation has shown that this rate is not limited by the TCP/IP performance, but by the driver performance. Therefore, a better driver implementation will increase throughput further. Some improvements to the default IPC are still possible. The performance of IPC for local processes is estimated to be about 43% of the memory bandwidth. The interaction of computation and communication is significant. An experiment has shown that the additional load on the machine greatly decreases throughput
