[jboss-jira] [JBoss JIRA] Commented: (JGRP-1133) NakReceiverWindow: make faster

[Bela Ban (JIRA)]

    [ https://issues.jboss.org/browse/JGRP-1133?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12571999#comment-12571999 ] 

Bela Ban commented on JGRP-1133:
--------------------------------

Performance on a 4 cluster system is roughly 143MByte/sec/node, so this is good enough for now. Before we continue optimizing NRW, Retransmitter and TimeScheduler(2), we need to see what performance is on a larger cluster, e.g. 30 nodes.

I believe, however, that *flow control* [1] might be the more important bottleneck to optimal performance in a large cluster.

However, before assuming anything, I need to have access to a larger cluster to actually measure performance and see where the bottleneck is !
