This issue has been raised a few times before, and I agree with Padraic here.
The synchronization issue hasn't been that pressing before since the
SharedItemStateManager was using a workspace-global lock in any case, but with
recent work that is no longer the case, and I see the database synchronization
becoming a bottleneck.

> Remove synchronization from JNDI data sources
> ---------------------------------------------

> Key: JCR-1050
> URL: https://issues.apache.org/jira/browse/JCR-1050
> Project: Jackrabbit
> Issue Type: Improvement

>
> Using datasources one should be able to rely on the application server to
> manage PreparedStatement caches therefore pre-creating and holding onto the
> connection for long periods of time should not be needed. This relates to
> improvement JCR-313, however, that change did not address the benefits one
> could see in using an application server controlled datasource. Even if
> jackrabbit does aim to use an embedded database such a system could be
> configured to use datasources and could benefit from the removal of the
> synchronization.
