Upgrading to HTTP 2

UPGRADING TO HTTP/2
2
HTTP/2 is fast approaching its first anniversary,
at which point browser support for SPDY will be
deprecated. Instart Logic has provided SPDY
support since 2014. We want to ensure our
customers that have been enjoying faster pages
with SPDY continue getting optimum performance,
so we have enabled HTTP/2 on the Instart Logic
CDN. We are happy to announce HTTP/2 support is
currently in beta and will be generally available
in the coming weeks. Content to end users will be
delivered over either HTTP/2 or HTTP/1.1,
depending on your users' browser support,
irrespective of your server configuration. End
users will see the benefits of HTTP/2 without
your organization needing to make infrastructure
changes.

I enabled HTTP/2 on a site that's being routed
through Instart Logic. The following waterfalls
compare a set of page elements being downloaded
via HTTP/1.1 versus HTTP/2 HTTP/1.1

HTTP/2 The parallel requests in
HTTP/2 results in the following improvements
Version HTTP/1.1 HTTP/2
Start Render 2.985 2.398
Speed Index 4672 2543

• Switching to HTTP/2 translates to a 20
  improvement in start render time and a 45
  improvement in speed index.
• Before switching to HTTP/2, we recommend you read
  this overview of HTTP/2 compatibility with front
  end optimization techniques with front end
  optimization techniques. Changing to HTTP/2 may
  make some optimizations you might have previously
  implemented obsolete.
• Once you have made the switch to HTTP/2, proper
  debugging, troubleshooting and validation tools
  are needed. Here are four to get you started
• Wireshark Wireshark added decoding in version
  1.12.0.
• HTTP/2 indicator This Chrome extension won't
  help debug, but it is nice to see the blue
  lighting bolt indicating your site is being
  served by HTTP/2. Clicking on the indicator opens
  Chrome Net internals in a new tab.
• Chrome Net Internals For debugging purposes,
  Chrome Net Internals displays live HTTP/2
  sessions with detailed information on sessions
  and frames. This can be accessed by clicking on
  the blue lightning bolt from above or by entering
  "chrome//net-internals/http2" into the Chrome
  browser.

  for a request.
