Many critiques are possible, both of the target (five seconds for first load), the sample population (worldwide internet users), and of the methodology (informed reckons). Emerging markets with high mobile internet use and dense populations can feature poor fixed-line broadband penetration compared with Western markets. In the U.S.,

Computer systems, from the Internet-of-Things devices to datacenters, are complex and optimizing them can enhance capability and save money. How many buffers are needed to track pending requests as a function of needed bandwidth and expected latency? Can one both minimize latency and maximize throughput for unscheduled work?

In almost every area, Apple's low-quality implementation of features WebKit already supports requires workarounds not necessary for Firefox (Gecko) or Chrome/Edge/Brave/Samsung Internet (Blink). After years of standards discussion and the first delivered to other platforms in 2018, iOS 14.5 Converging Views. Pointer Lock. Web Serial.

The new AWS EU (Stockholm) Region will have three Availability Zones and will be ready for customers to use in 2018. This enables customers to serve content to their end users with low latency, giving them the best application experience. Over the past decade, we have seen tremendous growth at AWS.

Estimated Input Latency tells us if we are hitting that threshold, and ideally, it should be below 50ms. Ah, and don’t use JPEG-XR on the web — "the processing of decoding JPEG-XRs software-side on the CPU nullifies and even outweighs the potentially positive impact of byte size savings, especially in the context of SPAs".

Globally in 2018–2019, according to the IDC, 87% of all shipped mobile phones are Android devices. Estimated Input Latency tells us if we are hitting that threshold, and ideally, it should be below 50ms. So additionally conducting research on common devices in your target group might be a good idea.

Estimated Input Latency tells us if we are hitting that threshold, and ideally, it should be below 50ms. Designed for the modern web, it responds to actual congestion, rather than packet loss like TCP does, it is significantly faster , with higher throughput and lower latency — and the algorithm works differently.
