Web performance is not just about moving static files closer to visitors, it’s also about ensuring that every page renders as fast and efficiently as possible from whatever device a visitor is surfing from. Cloudflare users can choose any combination of these web content optimization features that take performance to the next level.
Asynchronous resource loading optimizes your HTML so it renders as quickly as possible without waiting for slow scripts like widgets or advertising. Your web pages will feel much snappier.
Cloudflare Rocket Loader makes the Financial Times website (FT.com) faster, in spite of them already using a top-tier CDN to deliver their content.
The mobile device market is huge and continues to expand. As we look toward 2017, the number of active mobile devices will grow to over 5 billion. Cloudflare recognizes the high expectations of mobile users and this is why we’ve custom-built a technology (Polish & Mirage, Native Mobile App Acceleration & Security, Custom Cache Key, etc.) that provides seamless mobile experience. Cloudflare empowers web businesses to deliver fast, secure, and device specific content to enhance the experience of mobile users.
A content delivery network (CDN) takes your static content and stores a copy closer to your visitors. By moving the content closer to your actual visitor, it takes less time to access the resources, which means the page loads faster. Content delivery networks have been around for the last 15 years. Nearly every large website on the Internet uses a CDN.
Web content optimization (WCO) improves the way the resources on your web page load. Websites are collections of multiple apps, widgets, and tags that include everything from the ad network code inserted on a page to a Twitter Retweet or Facebook Like button. WCO ensures that these resources that make up your web page load optimally. While CDNs have been around a long time, WCO is a newer development and takes performance to another level.
We built our own CDN from the ground up. We used the latest technologies like solid state drives for screaming I/O and Anycast routing and geo load balancing to make it as fast and efficient as possible. But we didn’t want our efforts to make the web faster to stop with the traditional CDN. Cloudflare’s Rocket Loader and other WCO services ensures your page renders as fast and efficiently as possible. By using both CDN and WCO, your site is optimized both at the network and browser level.
Automatically detect the pages that are most likely to be accessed during a session from the traffic patterns of all the users visiting a site.
Polish automatically applies both “lossless” and “lossy” image optimization to remove unnecessary bytes from images. On average, image sizes are reduced by 35%.
Mirage accelerates image delivery for your visitors based on their device. Mirage detects screen size and connection speed to optimally deliver images for the current browser window, mobile or desktop. Learn more
