OpenCDN Project Home Page. Globule: the Open-Source Content Distribution Network. Make your website faster using Content Delivery Network - Omar A. Every request from a browser goes to your server traveling through the Internet backbones that spans the world.
The number of countries, continents, oceans a request has to go through to reach your server, the slower it is. For example, if you have your servers in USA and someone from Australia is browsing your site, each request is literary crossing the planet from one end to the other in order to reach your server and then come back again to the browser. If your site has large number of static files like images, css, javascript; sending request for each of them and downloading them across the world takes significant amount of time. If you could setup a server in Australia and redirect users to your Australian server, then each request would take fraction of the time it takes to reach USA. Not only the network latency will be lower but also the data transfer rate will be faster and thus static content will download a lot faster.
