Ya I would have to agree with you tracker. Ever 3rd party dependency is introducing another DNS lookup. The whole point behind using a CDN effectively, besides lowering latency, is to reduce your DNS lookups to a bare minimum. For example, I use <a href="https:&#x2F;&#x2F;www.keycdn" rel="nofollow">https:&#x2F;&#x2F;www.keycdn</a>. They support HTTP&#x2F;2 and HPACK compression along with Huffman encoding which reduce the size of your headers.<p>The benefits of hosting say Google Fonts, Font Awesome, jQuery, etc. all with KeyCDN is that I can take better advantage of parallelism if I have one single HTTP&#x2F;2 connection. Not to mention I have full control over my assets to implement caching (cache-control), expire headers, etags, easier purging, and the ability to host my own scripts.
