Re: Optimizing Site
Taking a peek at your source, shows you have a bunch of links and images in your header that are being called through HTTPS. I am assuming that this is so there are not errors thrown during login or checkout, however this may be part of the problem with speed.
The background images really should be called using relative addresses through the CSS instead of being hardcoded with absolute addresses. The same rule of relative vs absolute URLs for the links will allow them to work better too.
Please do not PM for support issues: a private solution doesn't benefit the community.
Be careful with unsolicited advice via email or PM - Make sure the person you are talking to is a reliable source.
