We probably need some more details to help you out:
How much memory does your machine have?
Why is your MaxPermSize so large?
What sort of problems is Dojo running into? You don't want the debug option on a production server.
If you have a lot of RAM, increase your Xmx, and set Xms to the same value as Xmx.
With -Dexo.product.developing, it will be slow.
Would be better to debug why the merge/compression of Dojo is screwed up. Have you look into this yet ?
Yes it because of this bug I think, it is really painfull, I developped all my project based on GateIn and because of one bug I can't use it. And GateIn exclude to use a CDN too...
Do I have to wait to the 3.2 version or do I have to use another portal?
The issue of the other Jira is not about Dojo so it may or may not be related.
It won't be fixed in 3.2 if we don't have a fix Please help.
And what do you mean by CDN ?
