Theme Load Time Is Slow

My client is loving the Enfold theme, and it’s the only one I find myself using these days because it’s the BEST one on the market. Here is the problem. http://themecheck.org gives it a validation score of 0 % and the page load speed is 9-12 seconds, way too slow for Google. Seems to have image issues, even though I have made all my images to fit in the full width slider area.

https://developers.google.com/speed/pagespeed gives it a score of 48/100
Here is what they I need to fix:
Optimize images
Eliminate render-blocking JavaScript and CSS in above-the-fold content
Reduce server response time
Consider Fixing:
Enable compression
Minify JavaScript
Minify CSS
Leverage browser caching
Minify HTML

Please, any help is truly grateful, I don’t want to change this theme, or install on client sites, only to piss of Google.

Best,
Joshua
