Hi,

I have done a RCP with GMF and hibernate and I use TENEO as described on
the elver site.

The root I use is the Eobject "Dataset".
I have created 2 datasets
the first dataset contains more than 8000 EObjects
the second contains only 20 EObjects.

1st problem :
When I open my first dataset, it is very slow, it takes a very long time
even if I open just a partial diagram containing something like 50
EObjects.

2nd problem :
When I open my diagram on my 2nd dataset with 20 EObject, It takes a very
long time as if it watches the all database.
If I create a new Dataset which is empty and I connect to my dataset, it
takes a very long time to open it.

to te contrary, If I have nothing in my database and i create my first
dataset, when i launch it, it is opened very quickly

Is there a problem with teneo or something else?
I'm worried for the RCP I'm working on, because I have very catastrofic
performances when my database grows up

thank's by advance
