CloudFlare, We Have a Problem
While I agree with many of the points made, his estimation of the number of round trips is <i>way</i> off.  For a start, TLS negotiation requires several round trips before you even start speaking HTTP.  Secondly, browsers (depending on vendor, version and number of domains) have a limit to the number of in flight requests.  Thirdly, many pages load some assets via javascript execution, which adds another set of round trips.<p>As Cloudflare are <i>very</i> widely peered (I think they are now the most widely peered company), and as such are almost certainly closer to the end user than the origin server.  This does really matter when making lots of round trips, which is in practice closer to inevitable (unless you have a small SPDY or HTTP&#x2F;2 site, which is approximately no one).
