Also, media, software, and documents all take a significant amount of time to load, so it is essential to take action to ensure that your site loads faster than normal. Many webmasters believe that getting rid of assets is the most effective way to speed up their sites, but this isn’t the case! Instead, it is best to rely on a CDN.
How The CDN Works
As mentioned above, a CDN is capable of speeding up your website and making it load much quicker. How is this possible? Well, the CDN is actually a type of distribution network of servers, which maintain cached versions of your site and all of its content.

- The server, which is currently most available and has the highest level of server performance
Take note that the CDN will utilize a number of different techniques, in order to lower load times. Some of these will explored below.
- Load Balancing – The CDN is capable of balancing out the load and sharing the responsibilities among various servers and caches.
