[infinispan-issues] [JBoss JIRA] (ISPN-1523) Remote nodes send duplicate invalidation messages

[Dan Berindei (Commented) (JIRA)]

    [ https://issues.jboss.org/browse/ISPN-1523?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12642339#comment-12642339 ] 

Dan Berindei commented on ISPN-1523:
------------------------------------

Manik, it's not really incorrect, it's just suboptimal (I think) because each requestor gets the invalidation command numOwner times.

I'm not sure how big the performance difference would be if only the primary owner sent the invalidation command. I only noticed it because I had an exception breakpoint set for TimeoutException and one of the invalidation commands would hit my breakpoint (because the invalidation command tries to acquire the lock with 0 timeout).
