If someone has the same problem: 
I found a solution that works for me.

The Firebird .NET Provider Source contains 16 selects to the system tables.
I created tables for the resultset of each select  and a stored procedure that 
fills these tables.
Then I replaced the selects in the providers source code to select from these 
tables instead from the system tables and compiled it.

Result: 1 Min 20 Sec instead of 8+ Min for updating the Entity Model.

Greetings Reinhard

Yes, the query is same. Only amount of data transfered is not that huge. If 
you're on a fast line that will not make a difference.
