The upfront section of the site is taking ages to load

I've been working on my site using your spirit theme which looks and works great!
The only issue I'm having is that I can't get this down below a 5 second page load time
I've done all the advised tactics around minification etc, however, it's still pretty slow
On looking at Pingdom it looks like the upfront section of the site is taking ages to load...
