[support] Site performance (multiple views insert on node template)

Hello, I'm developing a site with ubercart and multiple views insert on a node template. As an example on http://www.janetjul.com/telas/blue-leaf <http://www.janetjul.com/telas/blue-leaf>the site has a slow load performance on the views inserted (3 jcarousel and 1 unfoirmatted view). Any idea of what to try? Thank's Pol
