Marcel Reutegger commented on OAK-2829:
---------------------------------------
Committed some changes to trunk to make it easier analyzing observation related
timing:
- Changed format of DocumentNodeState.toString() to avoid newline
- Introduce PerfLogger in ChangeProcessor
- Align threshold for PerfLogger in ChangeProcessor and NodeObserver to 100ms
Done in http://svn.apache.org/r1678171
> Comparing node states for external changes is too slow

> Comparing node states for local changes has been improved already with
> OAK-2669. But in a clustered setup generating events for external changes
> cannot make use of the introduced cache and is therefore slower. This can
> result in a growing observation queue, eventually reaching the configured
> limit. See also OAK-2683.
