We've been reviewing your site at various points thoughout the day and the delay noted above does seem to be rather consistent. That often indicates that you have a remote include (such as a twitter feed, weather data, an rss feed, etc.) that's causing a delay in the rendering of your page. For comparison purposes, please perform a clean Joomla install in a subdomain under your account and then provide us with the admin URL and superuser username/password if you still see those delays with a clean install, thanks.
