Subject Re: Cocoon 2 RC2 performance disappointment

Hi,

Don't get me wrong, I think Cocoon 2 rocks too. I want to keep working with
Cocoon.
But the combination of our developers having to experiment with the sitemap
(lack of documentation on actions and action sets) and the project not
delivering the right performance with Cocoon 2 makes life hard.

Greetings,

Michael
