Hi, I am very much worried about tuning my website's performance. I've just read an article by Shaun Walker with the following comment: "One solution we implemented in DotNetNuke 4.4.0 is a new "light weight" install model. Basically, DotNetNuke will only install a few basic modules by default. The other modules will exist in the /Install/Module folder ( with a different file extension ) and can be optionally installed through the Host / Module Definitions interface. The result is that you only need to install the modules which you need for your site - and the other modules will not unnecessarily contribute to your memory footprint."

My install is 4.3.4, so it has several unused modules installed, including store, contacts and a whole set of them. Actually, I use more third party modules than the core ones. Can I uninstall unused core modules without fear of having application problems? And would that result in performance improvement?
