[jboss-jira] [JBoss JIRA] (JGRP-1991) TCP_NIO2: copy on demand

[Bela Ban (JIRA)]

     [ https://issues.jboss.org/browse/JGRP-1991?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Bela Ban updated JGRP-1991:
---------------------------
    Description: 
When TCP_NIO2 writes data, we always pass a copy of data of it, because of JGRP-1961 [1].
However, if we copied the data only on a *partial write* (full writes don't need a copy), then we could always pass data from reused buffers down to the transport.

When TCP_NIO2 writes data, we always pass a copy of data of it, because of JGRP-xxx.
However, if we copied the data only on a *partial write* (full writes don't need a copy), then we could always pass data from reused buffers down to the transport.
