A Content Delivery Network (CDN) significantly enhances website performance primarily by reducing content delivery time. This is achieved through its architecture, which consists of a network of distributed servers located in various geographical locations around the world. When a user accesses a website utilizing a CDN, the server closest to that user is selected to deliver the content. This proximity minimizes latency, which is the time it takes for data to travel from the server to the user's device. As a result, users experience faster load times, leading to an improved overall browsing experience.

Additionally, CDNs can handle high traffic volumes and reduce the load on the origin server, ensuring that websites remain responsive even during traffic spikes. By caching content like images, videos, and web pages on multiple servers, a CDN not only accelerates delivery but also provides redundancy and reliability. This is particularly vital for global audiences, as it ensures that users experience consistent performance regardless of their location.
