Anyone knows how to fix files that stall the page load time. I know about the hosting, i will change the hosting. But how can you effectively defer these files that doesnt need to be loaded at first.
do you mean the optimized CSS files? If so then to defer them would mean loading them in the foot of the website which would most probably result in a FOUC.
I ran the site on GTmetrix and as you noted the Hosting is a big problem. I would look to resolve this first and then revisit the issue. Also note that the Shortpixel CDN is blocking, probably the slow redirects from the host server once again.
