People say JAMstack sites are fast — let’s find out why by looking at real performance metrics! We’ll cover common metrics, like Time to First Byte ( TTFB ) among others, then compare data across a wide section of sites to see how different ways to slice those sites up compare. TTFB mobile speed distribution (CrUX, July 2019).

A full-stack observability solution uses telemetry data such as logs, metrics, and traces to give IT teams insight into application, infrastructure, and UX performance. Observability can identify the baseline user experience and allow teams to improve it by optimizing page load times or reducing latency. See observability in action!

Google’s Core Web Vitals is a set of performance metrics that site owners can use to evaluate performance and diagnose performance issues. These metrics provide a different perspective on user experience: Largest Contentful Paint (LCP) Measures the time it takes for the main content on a webpage to load. One of the key Next.js

Compared to the most recent master version of libaom (AV1 reference software), SVT-AV1 is similar in compression efficiency and at the same time achieves significantly lower encoding latency on multi-core platforms when using its inherent parallelization capabilities. The plot shows the results of the 2-pass encoding mode in both codecs.

This is a complex topic, but to borrow from a recent post , web performance expands access to information and services by reducing latency and variance across interactions in a session, with a particular focus on the tail of the distribution (P75+). Consistent performance matters just as much as low average latency.

A Primer on Speed. Discussing performance and “speed” can quickly get complex, because many underlying aspects contribute to a web-page loading “slowly”. Because we are dealing with network protocols here, we will mainly look at network aspects, of which two are most important: latency and bandwidth. Congestion Control.

Many practical real-world problems have large and continuous state and action spaces… these can present serious issues for traditional RL algorithms. Another great insight here (which reminds me of discussions of system latency) is that ‘average’ performance (i.e., High-dimensional state and action spaces.

Few teams I’ve encountered have actionable metrics associated with the real experiences of their users. I can count on one hand the number of teams I’ve worked with who have goals that allow them to block launches for latency regressions, including Google products. And they do.

Each of these moments is experienced stochastically in our model, with the final moment presenting a previously un-hedged risk. Rendering text is important (think login screens), but there's no product without low-latency, adaptive codecs, networking, and camera/microphone access. It takes a lot to push a vibrant ecosystem to collapse.
