JXTA performance study

Project JXTA is the first peer-to-peer application development infrastructure that includes standard protocols and multi-language implementations. Performance and scalability of JXTA are not well understood, despite its widespread usage in research and increasing popularity in the industry. This paper reports on a performance evaluation of the JXTA protocol implementations in Java. The peer startup and pipe performance are evaluated for the JXTA protocol versions 1.0 and 2.0. The results show that the performance of the latter JXTA version has improved for secure message transfer and multicast propagation, but degraded for several other operations.
