Performance issue after EMF complex tree creation? [message #1744086]

Hello,

I created an EMF model.
There are of course code to refresh some tree nodes when modifying values.

I use EContentAdapter to observe some modifications on my Model.
It is quite complexed.

I use as well EMF Form. Each time I click on a node, I displays a view:
myECPSWTView.dispose();
myECPSWTView = ECPSWTViewRenderer.INSTANCE.render(parent, myQuoteObject);

I use Jubula to create a complete model.
Or even if I create a full model manually, my eclipse is slower at each click.
Even if I close the EMF model, create a file is slow too.

I thought about memory issue, try to increase jvm settings.
I try to disable the EMF Form view.
For the moment, no results. Still slow after a model creation.

Do you have some way to check what is going on? for memory? etc.?

Hi Jim,
can you show some code snippets, so that we see what exactly you are doing?
Can it be, that you add a econtentadapter every time you open you model without ever removing it?

why do you need the econtentadapter in the first place?

Cheers,
Eugen

Finally,

I found the reason.
It was not easy to find, but I did.

Thanks to the tool "Sleak", I was able to see that I instantiated Fonts for each cell.
So it stays always in memory, and my application performance suffered
progressively.

I was confident, but a bit stressed concerning performance.
Now everything is OK.

Thx
Rgds
Jim
