The first thing that we noted is that site you provided uses the CDN and does not use the cache, another your site (faster) uses the cache but does not have CDN. So, try to disable the CDN and install cache plugin at the first site. After that provide us with WP Dashboard access to your site and we’ll continue investigation why this site is slower than the previous one because the new version of our theme should demonstrate better results.
Also, tell me if both sites use the same server/hosting provider?
