-----------------------------------------
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).
