How to remove render-blocking javascript and optimize css in above the fold content?

The purpose of a CDN isn't to make your website load faster, though it could make some static files load faster depending on where the user is in relation to the host. Instead it is to offload static resources. If your using 10% of your CPU without a CDN then it likely isn't going to help. Instead make sure your using an op code cacher and memcache. These two things as well as vb Optimise Pro will speed your site up.

That being said it is recommended to have static content on a CDN for big sites. I have used MaxCDN as well as Cloudflare and I get better results from Cloudflare. It is also cheaper for me to run 2 sites and I can run everything through SSL. The DDoS protection is good and really an added plus for me.

A lot of people for some reason do not like Cloudflare and I can't understand why. It isn't the silver bullet but is a solid CDN and a good service. I have 1 site where it is saving around 75% request.

Here is one of my sites which is on a VPS (about to merge it onto my dedicated)

With cloudflare
