Accelerate Web Applications

Today's web pages are increasingly complex with a globally dispersed audience, which can degrade the user experience.

Cloudflare increases web application performance by bringing content closer to your users, caching static content on its network, optimizing image files, compressing dynamic content, routing requests to the least congested path, and much more.

Challenges Affecting Performance

Heavy, complex web pages

Average page size continues to increase due to complex CSS, high-quality images and video assets, or extensive usage of javascript snippets. Larger web page sizes (the ‘payload’) increases the amount of data which must travel over the network to be rendered by the visitor’s browser, slowing down loading speeds.

Interactivity and Personalization

When applications use APIs to fetch dynamic content to support personalization and interactivity, the number of connections and trips to origin infrastructure increases, resulting in performance degradations and poor visitor experiences.

Globally Distributed Visitors

As modern web page visitors become more globally dispersed, content must travel longer distances, sometimes to countries with slow or unreliable networks. For example, a website with an origin server in San Francisco might have an equal number of global visitors as it does local and global visitors will experience increases in latency.
