Back in 2016, I gave a talk outlining the causes and effects of the terrible performance of web apps built using popular tools on the fastest-growing device segment: low-end to mid-range Android phones. Modern network performance and availability. The cheapest (high volume) Androids perform like 2012/2013 iPhones, respectively.

It’s about ensuring that your front-end is also working perfectly, that your site can deliver a delightful experience to your users or customers, and that it is functional – even when it’s experiencing up to seven or more times the typical traffic load. Traffic patterns outside of normal [RUM or Analytics].

The best available proxy data also suggests that shared caches would have a minimal positive effect on performance. Removal also creates a performance cliff for content that assumes cache availability. One available proxy is the distribution of use from Google's hosted JS libraries. None of this holds. Thar be dragons.

Because the HTML parser stopped, all network traffic also stopped (because no other HTML tags were parsed to initiate HTTP requests). It's great that the async attribute is available and well known, but synchronous script loading is still the default. The number of sync dropped and async rose in June 2016. Enter the Preloader.

This was a keynote presentation at the “2nd International Workshop on Performance Modeling: Methods and Applications” (PMMA16), June 23, 2016, Frankfurt, Germany (in conjunction with ISC16 ). Here I assumed a particular analytical function for the amount of memory traffic as a function of cache size to scale the bandwidth time.

These organisations may perform incidental data collection (from business analytics tools, e.g.) but are inconsistently reviewing performance metrics or considering them when formulating KPI s and OKR s.
