Karim AMMOUS commented on JGRP-1765:
------------------------------------
Disable the loopback ensures as much as possible that the sender handles the message at
the same time as the other receivers.
Otherwise, with loopback, there are more risks the sender processes the data much before
the other members due to the network latency.
TP: enable loopback by default and discard own multicasts

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()}}
