Website performance talk: Delivering The Goods In Under 1000ms

Paul Irish (@paul_irish) gave a really good keynot presentation during Front End Ops Conference 2014 in SF. The title: “Delivering The Goods In Under 1000ms“.

He focuses on investigating the key question “page size vs. number of requests” what has a bigger impact on website performance.

“… latency is the performance bottleneck for HTTP and well … most of the web”

Aggressive, but good goals to achieve:

Deliver a fast mobile web page load

  • Show the above-the-fold content in under 1 second
  • Serve above-the-fold content, including critical path CSS, in first 14kb of response

Maximum of 200ms server response time

Speed index under 1000
