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
