Optimize in-memory object size ------------------------------ Key: JGRP-1745 URL: https://issues.jboss.org/browse/JGRP-1745 Project: JGroups Issue Type: Enhancement Reporter: Bela Ban Assignee: Bela Ban Priority: Minor Fix For: 3.6.8 Get the Java Object Layout tool from [1] and * Measure the size of objects which are frequently allocated in memory, e.g. ** Message ** Event ** Header subclasses (TpHeader, UNICAST3$Header, STABLE$Header, NakaAckHeader3) Try to remove fields which are not absolutely needed and / or can be moved into the superclass. E.g.: {{NakAckHeader2.sender}} might get removed: can't we determine the sender from the message ? (Maybe not, if sender is the original sender, not the sender of the message) [1] https://github.com/Sanne/java-object-layout
