[jira] [Commented] (OAK-4428) Optmize RevisionVector methods

    [ https://issues.apache.org/jira/browse/OAK-4428?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15315772#comment-15315772 ] 

Chetan Mehrotra commented on OAK-4428:
--------------------------------------

As can be seen in hot-methods-1.png
* It would better to cache the hashcode of RevisionVector
* Also the equals method would probably benefit from a reference equality check as the RevisionVector instance might be same

> {{RevisionVector}} is used in very critical paths and we should look into optimzing some of its critical method
