> Nuxeo suffers of huge performance problem while the repository is growing up 
> : 
> the navigation becomes more and more difficult and the problem origin is how 
> we are using NX_ALLOWED_ACCESS stored procedure : this and function is called 
> on each line of hierarchy table and the query planner of the database never 
> build subqueries, even if we set a huge cost to this stored procedure.
> So we have to manually build a sub- select for the user query and on this 
> result run  NX_ALLOWED_ACCESS.
