                 Key: JGRP-813
                 URL: https://jira.jboss.org/jira/browse/JGRP-813
             Project: JGroups
          Issue Type: Task
            Reporter: Bela Ban
            Assignee: Bela Ban
             Fix For: 2.7


Take a look at the following items (visualvm, -Xprof, -Xrunprof):
- FD: message counts as heartbeat: enable / disable this as it is overhead
- IpAddress: hashCode() can be more efficient. Take a look at equals(), too. Possibly get rid of canonicalization

Potential hotspots:
- NakReceiverWindow.stable()
- IpAddress.compare()
- Retransmitter.remove()
- Message: canonicalization cost (1 hashmap lookup/insertion) ?
