Interesting results, but let's think about a few things before we all switch to Cloudflare CDNJS. 1) Time to first byte. In my experience the biggest lag is the connection, not actually downloading the file (for small js, images, etc...) I don't know how to test this. 2) Caching, by using google for common libraries like jQuery your chance of the end client already having a local cached copy are much greater. 3) Reliability. I know google has been recently killing off it's products, and even I tweeted how they could break the internet by shutting off their hosted library API, but it's probably not going to happen. Can you say the same about cloudflare? I'm not saying I like one more than the other, but these are some things I would like to address before switching my and my clients sites over. One thing I will give a +1 to Cloudflare is the ability to add js to the CDN via github. https://github.com/cdnjs/cdnjs https://github.com/cdnjs/cdnjs
