Hi,

testing EEF generation with org.eclipse.emf.eef.tests.nonreg testcase result in dramatic preformances using acceleo.

With helios and 3.0 -> 26 s
With indigo and 3.1 -> 360 s

EEF launches 16 Acceleo generations one after the other, previously we put the emtl files in the resource set of the model and we didn't remove them. Now they are removed and each new generation (in your case) will reload them. I'll investigate this today but my opinion is that you spend most of your time loading your generator again and again...

The problem has been solved in EEF by switching to a single entry point for the generation. Closing this issue.
