Very Slow High End Loading

Hi,

I had you install the theme and demo data and the loading is very slow. I saw the thread about Bluehost and CDN use. Can you please let me know what the problem is so I can make the right decision.

This is what the hosting wrote me:
Analyzing the website slowness in detail, I see that slowness of 10 seconds is getting accounted from link hb-themes.com . Some of the reasons for the database driven website to load slow are unwanted plugins, trying to access external links from the website, themes etc. I suggest you to contact theme vendor to check slowness from http://hb-themes.com/themes/highend_wp/wp-content/uploads/ which is pointed to IP address 162.144.74.19 .
