yes, we suggest to start from W3 Total Cache plugin and it's proper configuration. Please also notice that on side speed, influence many different factors on which we do not have any impact like server speed for example.
Your configuration must be wrong then because as we proofed above, theme loads in less than 2 seconds what is very good result. You should contact with your admin or developer if you don't know what settings of W3 Total Cache plugin would be the best in reference to your server configuration.

P.S. As you can check on http://tools.pingdom.com/fpt/#!/O8W85/http://themes.muffingroup.com/betheme/ BeTheme is much faster than most of the WP themes.
Thanks!
