The host and theme you use to power your site play huge roles in its speed and overall performance. There are a number of different things you can do to improve upon this even further, but none are quite as effective as integrating your site into a content delivery network (CDN).
A CDN offers a way for you to balance the traffic your site receives across data centers located around the world. Not only does this improve performance, it makes your site more secure and protects against widespread DDoS attacks.
In this post, we list some of the best CDN providers available for the WordPress content management system.
