CDNs (Content delivery networks)
If you really want to make your WordPress website a speed machine you will probably need to use an external CDN network. There are a number of them. The one that I have used is Cloudflare, both the free and paid versions. However, be warned getting one of these CDNs setup so it really works correctly is little bit more difficult.
