I have been creating a website using Joomla 1.5.0 which is wonderful except for the fact that the site is loading extremely slow. The website is located at:
http://www.appliednetsec.net
It seems the server host (Dreamhost.com) thinks it is a Joomla issue as they said they have uploaded some static pages and they load instantly. Unfortunately, the joomla site can take upwards of 50 - 60 seconds to load.

Below you will find the information gathered from running the JTS-post : Joomla! Forum Post Assistant. I appreciate the help as it is much needed at this point.
Thank you,
Mark
Problem Description:
http://www.appliednetsec.net loads VERY slow.
Actions Taken To Resolve:
Been in contact with Dreamhost.com who has supposedly cleaned up the server to improve performance.
Enable Caching via the Global Configuration which did not help. It also stopped the sub items of (the solutions button) from opening.
