That performance golden rule still holds true today. However, that pesky 20% on the back end can have a big impact on downstream metrics like First Contentful Paint (FCP), Largest Contentful Paint (LCP), and any other 'loading' metric you can think of. 80% of end-user response time is spent on the front end.

As IT infrastructure has become increasingly distributed and complex, organizations face the challenge of aligning business objectives and end-user experience with the availability and performance of the IT infrastructure. Performance is mission-critical to these organizations. Why is this important and why do you need it?

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. Poor performance has a compound effect on user expectations at an ecosystem level. Live by the link, die by the link.

The newcomer to the scene was Cumulative Layout Shift (CLS), and, not surprisingly, it's the metric that's gotten the most questions. Does it correlate to user behaviour or business metrics in any measurable way? While I understand why score-based metrics add value, I'm a visual person. It's definitely worth a read.).

The recently revealed [Meltdown and Spectre] bugs are not just extraordinary issues of security, but also performance. The patches that workaround Meltdown introduce the largest kernel performance regressions I've ever seen. Some older kernels have the KAISER patches for Meltdown, and so far the performance overheads look similar.

TL;DR: performance budgets are an essential but under-appreciated part of product success and team health. Nobody is trying to do a poor job, and yet the results of a “completed” PWA project often require weeks or months of painstaking rework to deliver minimally acceptable performance. Partner meetings are illuminating.

Site performance is potentially the most important metric. The better the performance, the better chance that users stay on a page, read content, make purchases, or just about whatever they need to do. Google’s industry benchmarks from 2018 also provide a striking breakdown of how each second of loading affects bounce rates.

Because the average page is now 3MB in size, and this seems like a good time to pause, check our assumptions, and ask ourselves: Is there any reason to care about page size as a performance metric? And if we don't consider page size a meaningful metric, then what should we care about? They represent trends – that's all.

One definition of simple, but not a terribly useful one, would be a program that simply memorised input-output examples. Nothing in the authors approach actually tests for this, but the program cost metric used to evaluate generated programs encourages it: a program has lower cost for example, if it is free of conditional branches.
