My Dear Friend , Your Model is Saved in DB and as you said ,its 210 entities ,.....
I think most of the time is taken by your utility for fetching the entities ,converting them into in mem objects as required by GEF,
This has nothing to do with GEF ....
You need to concentrate on your Utility , as Given the Models to GEF , it paints within 2 sec(That to most of the time is taken in opening the Editor ) ,if your Diagram contains large amount of figures , probably it takes another 1 or 2 sec more ....
I'd recently performed tests to find out the time taken by GEF ..... I serialised the Entire Inmem model and deserialised it on open (I din count the time of deserialisation) after that it was like flash (it hardly took 2 sec for painting 20 figures and more than 50 connectors )
I truly Agree with your second comment , Thats because you might be following One Model -One EditPart -One Figure (so if you have 10 different types of model ,so is 10 Editparts and 10 figures )..... I Suggest you to reuse the Editparts ,if possible , There is one article on efficiently using GEF Editparts ..... (I cant post the link as this is my 4th post)
Regards

Hi Girish, thank you for your reply.
The model is not getting saved in the database, it is saved inmem.. infacct finally into a flat file.

When we reverse engineer 210 entities,
1. It takes about 1 minute to read the meta data etc... WHICH IS FINE.
I do not have a problem with this.
2. After storing the model inmem, THEN I am calling generate Diagram.. and therefore it takes 30 seconds miminum...
This is the issue..

How much time did it take on Deserialization + drawing the diagram? Was it considerably more?
.. and also... 20 Figures and 50+ connectors is fine... most EDBMS would have 200+ tables. I am sure, 20 figures would never have been a problem and would have generated real quick...
I am talking about 210 figures + 400(+) connectors (which is very common in Enterprise Wide DBMS )..
We also have test cases having 20 odd figures etc.. and we know that they do get generated quickly....
So.. What is the time you would normally get in that one??
Thanks
