[jboss-jira] [JBoss JIRA] Commented: (JGRP-1132) AckReceiverWindow: make non blocking

[Bela Ban (JIRA)]

    [ https://jira.jboss.org/jira/browse/JGRP-1132?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12508648#action_12508648 ] 

Bela Ban commented on JGRP-1132:
--------------------------------

maybe add2() can also remove OOB messages as it already holds the lock. There would be less contention between add2() and removeOOBMessages()

> Remove the lock acquired by AckReceiverWindow on adds and removes. Use a ConcurrentHashMap to make these operations non-blocking (well, besides the write lock on a CHM segment).
> This should yield better perf
