When processing an HTML page containing a script that utilizes jQuery, a web browser must first download the jQuery library file using a URL that's embedded in the HTML. Even when minified, the main jQuery library file is hefty (in excess of 80KB), particularly in the context of downloading to mobile devices over sluggish wireless networks.
One option for companies developing websites and applications that leverage jQuery is to serve the jQuery library files exclusively from a web server in the corporate data center. But for sites and applications that have large, dispersed user populations, a better option is to utilize a jQuery CDN (content delivery network) that caches the jQuery library files in a widely distributed network of servers that can be accessed by web clients. By serving the files to end users from locations closer to the users—rather than only from a single, far-off corporate data center—a jQuery CDN greatly improves the performance of web pages and web applications that rely on jQuery.
A jQuery CDN is especially valuable in the context of a mobile optimization strategy. By delivering superior jQuery mobile performance, a jQuery CDN can help your organization create dynamic, richly rewarding online experiences for users of smartphones and other hand-held devices.
Two reasons make Akamai the best choice for enterprises or content providers seeking the benefits of a jQuery CDN:
