Well not going as I would hope. I reviewed carefully: https://theme.co/apex/forum/t/customizations-performance/210
I also installed W3 TOTAL CACHE, and it caused problems with the site. The Home Page came up white. I had this problem with W3 TOTAL CACHE once before with an X-Theme. It could well be my fault. However, it did not work for me.
I purchased an added WP Rocket which I have had a good experience with pairing with the X-Theme. The options to Enable for Images, Enable for iframes and videos, Enable caching for mobile devices, and Separate cache files for mobile devices.
I deleted Hummingbird that I had tried earlier with no noticeable improvement for fear the two plugins might conflict.
My primary issue is the pause between the loading of the logo and the Hero Image upon startup. Please go to www.rayscountryham.com and that to which I refer. Any further suggestions for curing this problem would be appreciated. I think that the remainder of the site is running reasonably efficiently.
