7.0 and the Portlets

Hello

So I've been playing around with the portlets and it's pretty cool but I noticed this behavior where if you're editing/changing one of the PP protocol containers the other containers get refreshed. I thought with AJAX that this behavior wouldn't happen. It would only update the existing container.... Also I wanted to get a sense on performance using Liferay/Tomcat.... it seems a bit sluggish but just wanted to see what other people think...

cheers
