Known as latency, it's the annoying delay that occurs between when you ask to load a web page and when its content actually appears on the screen. This delay interval can increase or decrease depending on a number of factors, many of which are specific to the web page in question. In all cases, however, latency is also affected by the physical distance between your audience member and your website's hosting server. The mission of a CDN is to shorten this physical distance, with the goal being to improve the speed and rendering performance of the site.

The best ones use sophisticated caching rules to capture copies of your site and distribute them to multiple nodes on the network. Beyond improving page load speeds, CDNs offer additional benefits: Better handling in high traffic situations, both legitimate and in the event of a Distributed Denial of Service (DDoS) attack Block spammers, bots and other malicious agents Reduce bandwidth consumption Balancing traffic loads between different servers Incapsula, for example, has found that websites using its CDN load up to 50% faster and use up to 70% less bandwidth.
This kind of performance increase is hugely beneficial for site owners facing large bandwidth bills and for site visitors who expect faster load times. 4. Be stingy with redirects One thing to consider if you're migrating your site is to try to avoid 301 redirects whenever possible. A 301 redirect is a permanent redirect from one URL to another. For example, the blog section of your site might have started at http://blog.examplelink.com , but you might want to move it to http://examplelink.com/blog for SEO reasons . In this case, you'll need to set up 301 redirects for all pages originally on the subdomain to the subfolder's URL structure, to make sure you don't lose all the traffic and juice.
