Hi @ockographics,
I had a similar problem with speed and used the health check plugin https://www.ads-software.com/plugins/health-check/ which was recommended to me by Elegant Themes ( I build with DIVI theme also) and it found problems that I was able to adjust on my hosting that helped, and my final issue was the CDN I was using, I ran performance tests on cdnplanet.com and found that my cdn was much faster in Europe, Russia, and Vietnam so I changed the cdn I was using and got things up to speed.
So, I thought I would mention these two things, it looks like the cdn you are using is being run by comcast cable network in the USA.
Good Luck!
Robin
