[ https://issues.apache.org/jira/browse/ZOOKEEPER-873?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13422494#comment-13422494 ]
Bill Bridge commented on ZOOKEEPER-873:
---------------------------------------
This is a simple localized fix with a low probability of causing any problems. I want to do this to learn the process for making ZooKeeper contributions.

> Currently, the leader is elected based on the length of its history. In heterogeneous settings, other processes can be better suited to serve as a leader, e.g., the process running on the node with best links to a majority. POLE (Performance Oriented Leader Election) will be a leader election implementation that takes into account multiple factors when selecting the leader.
