#ASKTHEINDUSTRY 08: Should you really compress all your initially rendered content into 14KB of data?

Yes. If you care — and you should! — about having your content rendered on your user’s mobile device in under a 1000ms you basically have not many other options.

First of all, in that 1000ms of time your user’s browser needs to:

  • Perform a DNS lookup
  • Perform a full network roundtrip to perform the TCP handshake
  • Send the HTTP request (which takes another full roundtrip)

On average, on a 3G connection, this leaves you just 400ms to:

  • Compute the response on the server
  • Layout and render the content on the browser

In such a scenario, it is vital that you minimize the additional roundtrips needed to perform the first render, in order to hit the 1000ms mark. Optimally you’d want no additional roundtrip, which brings us to the 14KB.
