Without more insight into all the assets you’re trying to load, I suspect much of that is caused by a ton of plugins.
If you’re using HTTPS here, you get the advantage of HTTP/2, which will load your resources in parallel. This reduces the need to Combine or Parallelize many of your resources.
Leverage Browser Caching should already be turned on here, but you may want to increase the Cache time in Cloudflare’s Caching tab.
As for your 7 second load time, more cache HITs will help. You can check the cache status by scrolling down in Pingdom and expanding the waterfall view for each asset.
Also keep in mind that anything that’s not loaded from your site (Google Fonts, etc), can’t be adjusted for better performance.
