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.

While this core is stalled on the TLB miss(es), it is best to dispatch RPCs to other available cores on the server. 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. Introducing RPCValet.

Recall that Cupertino manages the actual work of Safari engineers through Apple-internal systems (previously named "Radar" ), making public bug reports a sort of parallel track; once an issue is imported from a public bug to a private tracker, it's more likely to get developer attention.

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. Additionally, even if we knew the available physical bandwidth, that wouldn’t mean we could use all of it ourselves. Congestion Control.

Tools and CI systems help them monitor progress & prevent regressions. If our example document wasn’t reliant on JavaScript to construct the <my-app> custom element, the contents of the document would likely be interactive as soon as enough CSS and content was available to render meaningfully. 400Kbps transfer.

Long FMP usually indicates JavaScript blocking the main thread, but could be related to back-end/server issues as well.
