This theme is too slow even on fast server. Too bulky and set up is very hard to get working and too get the theme looking nice. Lacks the design elements I was expeting so cannot create the site I was looking for using this theme.
Please make sure to use performance plugin like W3 Total Cache, which allows to setup page caching:

I have been using this theme for 2 years. Graphic design is impecable. Functionality just works as desired. Bugs are being fixed. Updates keeps coming. Customer support exists (if you pay for extension of course).
I cannot ask more, I am giving you my 5 stars here.
The theme itself is nice, but the support for it is almost non-existent. They boast about customer satisfaction, but if you look through their update history, they are long delayed and usually not updated to the latest versions of the plugins. This is important as well, since they modify and rebrand the VC plugin, meaning that even if you wanted to update the plugins yourself, you cannot since you are reliant on there modified versions instead.
