[jboss-jira] [JBoss JIRA] (JGRP-1418) Avoid outoboxing on org.jgroups.stack.AckSenderWindow.get(long)

[Bela Ban (JIRA)]

     [ https://issues.jboss.org/browse/JGRP-1418?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Bela Ban updated JGRP-1418:
---------------------------

    Fix Version/s: 3.1


I'll take a look. Optimized structures will be tackled in https://issues.jboss.org/browse/JGRP-1394.

I'm fairly certain I can make retransmission in UNICAST and UNICAST2 similar to NAKACK2, so we wouldn't need ARW and ASW anymore...

> In certain scenarios the org.jgroups.stack.AckSenderWindow.get(long) method is invoked frequently, and each long is converted in a Long, becoming an allocation hotspot.
> I'm wondering if the ConcurrentNavigableMap used in AckSenderWindow could be converted in a more primitive-friendly collection.
