NAKACK2/UNICAST3: faster acceptance test ---------------------------------------- Key: JGRP-1766 URL: https://issues.jboss.org/browse/JGRP-1766 Project: JGroups Issue Type: Enhancement Reporter: Bela Ban Assignee: Bela Ban Fix For: 3.5 In NAKACK2/UNICAST3, when a message batch is received, we check every single message for presence of the corresponding header. If present we accept (and later process) the message. A faster acceptance test would be to check if the destination of the message batch matches, e.g. * UNICAST3: {{MessageBatch.getDest() != null}} * NAKACK2: {{MessageBatch.getDest() == nul}} If these conditions are false, we simply pass the batch up. This is faster than iterating through every message in the batch. Same for single messages: this is already done in UNICAST3, but not in NAKACK2.
