Cloudflare not working - Website stay slow

I bought a PRO plan to speed up site loading. I turned on WebP Lots, Mirage, Code Minification, and everything that went. But the web is still slow. Do you have any tips about what to do with it? Can’t I need to buy some additional apps? Thank you all for your advice.
