[ http://jira.jboss.com/jira/browse/JGRP-495?page=comments#action_12361168 ] Bela Ban commented on JGRP-495: ------------------------------- oob_loopback_msgs seems to have been the culprit; we added messages (even regular ones), but only removed OOB messages, causing this hashmap to grow indefinitely ! Testing with 3 million messages each (2 nodes) works... will need to do more testing, with larger message sets. Result for 2 nodes, each sending 3 million 1K messages: 17800 messages/sec: -- results: 192.168.5.2:3464: num_msgs_expected=6000000, num_msgs_received=6000000 (loss rate=0.0%), received=6GB, time=335687ms, msgs/sec=17873.79, throughput=17.87MB 192.168.5.2:3474 (myself): num_msgs_expected=6000000, num_msgs_received=6000000 (loss rate=0.0%), received=6GB, time=335969ms, msgs/sec=17858.79, throughput=17.86MB combined: 17866.29 msgs/sec averaged over all receivers (throughput=17.87MB/sec) -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://jira.jboss.com/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira
