Jukka Zitting commented on OAK-413:
-----------------------------------
I'm working on OAK-391 to come up with a way to use NodeBuilders more
effectively in TreeImpl so that we wouldn't need to call snapshot() so often.
> TreeLocation.getStatus() cost increases as more content is read below this
> location

> Issue Type: Bug
> Components: core
> Affects Versions: 0.5
> Reporter: Marcel Reutegger
> Attachments: OAK-413.patch

>
> The more content is read below a given location the more expensive the
> getStatus() becomes on that TreeLocation. There seem to be two issues:
> - Reading creates snapshots in MemoryNodeBuilder depending on how the tree is
> accessed.
> - Cost for comparing states also increases as snapshots are created for
> NodeStates.
> I'll attach a test that shows the described behaviour.
