------------------------------------------------------------------------------
+ jackrabbit works fast and was tested with several millions of items of real-life data and
depending on the persistence manager used little to no performance degradation was noticed.
see http://article.gmane.org/gmane.comp.apache.jackrabbit.devel/3977.
+ 
+ Bellow there are a few comments about some issues that might affect the performance.
+ 
  Regarding the tree structure. Since each parent holds references to its children each time
you add a child the parent becomes heavier. It causes a degradation in performance for write
operations according to the number of children. I think it's better to use a deep hierarchy
rather than a flat structure. I would recommend you to do some testing to establish the limits
that suits your needs.
  
  Regarding node references. The problem described above also affects node references, i.e.
adding a reference to a highly referenced node will be slower each time. IMHO this problem
prevents a very common use case, i.e. tagging.
