[jira] [Commented] (JCR-3335) Reduce synchronized block scope when
loading a node by id
[ https://issues.apache.org/jira/browse/JCR-3335?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13292828#comment-13292828 ]
Julian Reschke commented on JCR-3335:
-------------------------------------
(funny enough, I was looking at this as well :-)
Comments:
- we have that pattern in both getEntries(NodeImpl) and getEntries(NodeId), so we should fix them both
- once we have separated read from write operations, we may want to consider replacing the simple monitor by a ReadWriteLock...
Question: do we have test coverage for multithreaded access?

> This is a small(ish) change that takes the 'getNodeById' cll outside of the synchronized block that wraps the cache access.
> I see the load call as a heavy one, and the proposed change offers better concurrency behavior.
> In the tests that I ran, mostly related to queries I got a 20% improvement on average query response time.
