Marcel Reutegger resolved OAK-1361.
-----------------------------------
Resolution: Fixed
DocumentNodeState now uses the same diff mechanism as KernelNodeState on
DocumentMK when there are more than 10 child nodes to compare.
Fixed in http://svn.apache.org/r1562455
> DocumentNodeState#compareAgainstBaseState too slow

> Key: OAK-1361
> URL: https://issues.apache.org/jira/browse/OAK-1361
> Project: Jackrabbit Oak
> Issue Type: Improvement
> Components: mongomk
> Reporter: Michael Dürig
> Assignee: Marcel Reutegger
> Labels: observation
> Fix For: 0.16
>
>
> {{DocumentNodeState#compareAgainstBaseState}} usually falls back to the
> default implementation in
> {{AbstractNodeState#compareAgainstBaseState(NodeState, NodeStateDiff)}},
> which is slow. See also the TODO in the code. This negatively affects
> performance when generation observation events.
