Starting with release 12.1.3, Oracle Tuxedo offers the option to significantly enhance performance of Tuxedo applications with use of shared memory queues instead of IPC Message Queues for inter process communication on the same Tuxedo node. With the use of shared memory queues, the sender and receiver processes can exchange pre-allocated messages in shared memory, thus eliminating the need to copy messages several times before message reaches its intended target and resulting in much better throughput and lower latency.
