Hey There!
I have had the generator set up and working for about a month now. Usually it took around 12-13 hours to process my entire site. Over the last couple of days it's been taking 42-43 hours. I have not changed the site that much, only a few new pages have been added, but also some have been removed (dynamic content).
As the script is running longer, its now running during the day - so users are experiencing slow site performance.
I will PM my login details.
