What is a CDN and how does it help with Nextcloud performance?

A CDN (Content Delivery Network) is a network of servers distributed around the world. When a user requests content from your Nextcloud instance, the CDN delivers the content from the server closest to the user, reducing latency and improving load times. For Nextcloud, a CDN like Cloudflare distributes your files across multiple edge servers, enabling faster downloads and a better user experience.
