Proof-of-concept: Java Real Time 2.1 on Solaris 10
DTrace Aids in Identifying Latency Causes

A duel in the Suns of sorts involving a Sun Fire V40z and a Sun Fire X4450 connected back-to-back was performed to discover their ability to exchange UDP or TCP messages with a round-trip latency under 100 ms per message. In addition, both servers were occupied with some business logic, to bring the overall CPU utilization to 60-80% on each machine. Both were running Solaris 10 Update 5 and Java RTS 2.1 (build 1.5.0_16_Java-RTS-2.1_fcs-b11_RTSJ-1.0.2). Frederic Pariente reports the results in his blog "Real Time opens system and network surveillance to Java," a proof-of-concept to evaluate Java RTS 2.1 on Solaris 10.
