In most cases, a Guest LAN or Virtual Switch Guest LAN would be the way to go. HiperSockets would be my second choice. Shared OSA third. That is for inter Guest communication. HiperSockets may be faster for very large data streaming applications, but may not be noticeably different for a lot of workloads. HiperSockets and Shared OSA would also require more locked memory than Guest LAN or Virtual Switch. See http://www.vm.ibm.com/perf/reports/zvm/html/ for detailed measurements.
