Do I need to add cloudflare to the login page?

[wamm666]

Hello everyone, I follow the guide of @servandosilva, https://servandosilva.com/upload-landing-pages-vultr/ the login page is laid out, but after testing the speed is not ideal, may I need to add cloudflare? If you need to add , How can I add it? Because DNS has already pointed to vultr. Thank you all for
