>                 URL: http://tracker.firebirdsql.org/browse/CORE-3560
>             Project: Firebird Core
>          Issue Type: Bug
>          Components: Engine
>    Affects Versions: 2.5.0
>         Environment: Windows family
>            Reporter: Jesus Angel Garcia Zarco
>            Assignee: Alexander Peshkov

> When the user connects to my application, executes one stored procedure to 
> register the user login. This stored procedure update one table that force 
> the load of most of the metadata in memory.
> The difference is that while Firebird 2.1.5 uses 57100 Kb, Fb 2.5.1 uses 
> 84100 Kb, that is a 47% more memory than 2.1. once executed the procedure and 
> starting to work with the application, the memory consumption increases in 
> parallel. That implies that for 200 users the less memory needed for 2.5 is 
> near 16 Gb, while for 2.1 is near 11 Gb that is a big difference.
> That implies that classic server will use per connection so much memory. I 
> don't know if is a bug or not, but the difference is so much. If classic 
> server is for complex enviroments with high load, then  
> Steps to reproduce the issue: Connect to the database and execute procedure 
> usuario_entrada( 0, '', 'STATION01', '' )
