Subject [jira] Updated: (JCR-1705) Reduce memory usage of transient nodes
Date Wed, 06 Aug 2008 14:06:44 GMT

     [ https://issues.apache.org/jira/browse/JCR-1705?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Marcel Reutegger updated JCR-1705:
----------------------------------

    Attachment: JCR-1705.patch

Once more, but now back to more readable size ;)

The new patch only includes the memory improvements. Moving the child node entry classes has
been solved in a separate issue (JCR-1710).

> When adding lots of transient nodes, most of them don't have child nodes because they
are leafs. The attached patch initializes NodeState.childNodeEntries with an unmodifiable
empty ChildNodeEntries instance and turns it into a modifiable one only when needed.
> Running a test with 100k nodes (10 children per node) the memory consumption for child
node entries drops from 42MB to 12MB with this patch.
