             Summary: Do length check first before actual byte check in compareBytes method of Utils class
                 Key: ZOOKEEPER-3058
                 URL: https://issues.apache.org/jira/browse/ZOOKEEPER-3058
             Project: ZooKeeper
          Issue Type: Improvement
          Components: jute
            Reporter: Hosur Narahari


In compareBytes method of org.apache.jute.Utils class, all the individual bytes of 2 byte arrays are compared and then their lengths are compared. We can improve the performance by first having length check, since we can rule out that they aren't equal by a single if condition(O(1) operation) rather than looping through arrays(O(n) operation).
