grip, thanks for your request. Let me explain how the software works.
When site has no pages, the software automatically publishes some pages and start building content on these new pages (the final content depends on modules you have enabled). Automatic Website Builder does NOT use duplicated and useless "copy/paste" articles like cheap website creator tools do; it builds 100% unique content. Usually it takes 1-5 seconds to build a new page (depends on server and software settings configured by user).
The same happens when new pages need to be published (every 24 hours).
However, the software builds new pages only once a day (unless you force content building engine to be launched via administration interface) and published pages are loaded right from MySQL database, so no performance issues should be noticed. If you experience any performance issues, it might be because one of these reasons:
1. The number of pages being automatically built is very high. You can change it via administration interface.
2. mySQL service is not properly optimized on server.
3. Server connection is slow. The software automatically parses many remote places (youtube, image sites, news portals, and so on) when publishing new pages, and if connection is slow, it might take some time.
Hope that helps.
