Buildings, food and transport have a much bigger carbon footprint than IT globally. In the simplest case, you have a growing workload, and you optimize it to run more efficiently so that you don’t need to buy or rent additional hardware, so your carbon footprint stays the same, but the carbon per transaction or operation is going down.

The focus of optimization hence will completely shift to efficiently handling RPCs at the endpoints as soon as they are delivered from the network. Any resulting load imbalance after applying these [RSS] rules must be handled by system software, introducing unacceptable latency for the most latency-sensitive RPCs with µs-scale service times.

Government agencies aim to meet their citizens’ needs as efficiently and effectively as possible to ensure maximum impact from every tax dollar invested. Critical infrastructure and services refer to the systems, facilities, and assets vital for the functioning of society and the economy.

An often used metaphor is that of a pipe used to transport water. One aspect of performance is about how efficiently a transport protocol can use a network’s full (physical) bandwidth (i.e. Passing this data is done using kernel APIs (system calls), which involves a certain amount of overhead per API call.

Tools and CI systems help them monitor progress & prevent regressions. Some systems show median RTTs near ~100ms for 3G users. Contended, over-subscribed cells can make “fast” networks brutally slow, transport variance can make TCP much less efficient , and the bursty nature of web traffic works against us.

On the other hand, we have hardware constraints on memory and CPU due to JavaScript parsing and execution times (we’ll talk about them in detail later). Gatsby (React), Next.js (React), Vuepress (Vue), Preact CLI , and PWA Starter Kit provide reasonable defaults for fast loading out of the box on average mobile hardware. ??Also,
