TP: enable loopback by default and discard own multicasts --------------------------------------------------------- Key: JGRP-1765 URL: https://issues.jboss.org/browse/JGRP-1765 Project: JGroups Issue Type: Enhancement Reporter: Bela Ban Assignee: Bela Ban Fix For: 3.5 Enable {{TP.looback}} by default (deprecate and ignore prop): all messages sent by self are passed right to a thread pool to send them up again. When a multicast message sent by self is received, it is currently passed to a thread pool, de-serialized and only then discarded if loopback=true. This means that we create an unneeded buffer for de-serializationand perform de-serialization. SOLUTION: discard the multicast from self immediately when receiving it, in {{TP.receive()}}
