Some of my clients have huge websites using RvSiteBuilder and when they are publishing it takes forever to publish, and some times i have to raise the memory and time of execution on cPanel.

It will be great that users when in Step 7 have an option only to publish the new pages or updated pages.

Thanks in advance.

We are working on it. New publishing system will request to publish 1 page then make a new request to create a next page until finish. It will solve the timeout and memory usage issue. To do that, we need to change RVSiteBuilder to UTF-8 allowing us easily working on AJAX. We will releaase this as v4.0.
