             Summary: Improve Queue Usage in QuorumCnxManager.java
                 Key: ZOOKEEPER-3340
                 URL: https://issues.apache.org/jira/browse/ZOOKEEPER-3340
             Project: ZooKeeper
          Issue Type: Improvement
          Components: server
            Reporter: David Mollitor


I was recently profiling a on a ZK Quorum Leader in a low-volume environment and noticed that most of its time was spent in {{QuorumCnxManager#RecvWorker}}.  Nothing wrong with that, but it did draw my attention to it.  I noticed that {{Queue}} interactions are a bit... verbose.  I would like to propose that we streamline this area of the code.
