   * org.apache.jackrabbit.core.persistence.bundle.Oracle9``Persistence``Manager (Oracle 9)
   * org.apache.jackrabbit.core.persistence.bundle.Bundle``Db``Persistence``Manager (generic
database)
  
- Bundle persistence managers store each node together with all the properties as one unit.
If you have large binary properties, please also use DataStore or BLOBStore, otherwise the
performance can get worse than non-bundle persistence managers.
+ Bundle persistence managers store each node together with all the properties as one unit.
Large binary properties are stored to the BLOBStore by default (or DataStore if configured).
Setting the minimum blob size for bundle persistence managers very high decreases the performance.
  
  Storing the data in the file system does not require a database. Depending on the file system
and database, database persistence managers are sometimes slower and sometimes faster than
the Bundle``Fs``Persistence``Manager. When using a database, please note that embedded Java
databases do not have network overhead.
