Site is abysmally slow

Hello,
I’ve spent hours and hours duplicating the WordPress site from my local server to a live server and it’s been terribly slow trying to configure what the issues are. I googled it and I came to many threads on caching, optimizing, CDN..etc
I came across this:

1. Optimize all images with AI/Photoshop before uploading to server ‘save as web safe’ jpg
2. Once all images are on the website optimize with ewww optimizer plugin twice 1hr 10mins apart.
3. Install wp-smushit run once to remove jpeg extra data, then uninstall.
4. Use BWP minify plugin to minify scripts and stylesheets.
5. Install WP-Super cache, select all recommended settings.
6. Logout your website, visit every page at least once to create super cache files.
7. Join Cloudflare setup your website on their CDN, Choose options: Full CDN Optimisation save then activate purge files. once done log out.
8. Have a cup of coffee.
9. Visit your site after 20 minutes or so.
10. Don’t forget to smile.

Regards,
Ismael

My issue is that since my live site is so slow, I can’t even get to step 2 without spending an hour waiting because it’s loading so slow. So I did all those steps in my local site, but it’s hard to gauge whether it works or not since it loads pretty fast. I migrated it with all the plugins and settings in place but my live site still slow as heck. http://cm3.angelkao.com/ is the website.

Please help me with this
