The usual caveats also apply: Performance is a deep and nuanced domain, and much can go wrong beyond content size and composition. How sites manage resources after-load can have a big impact on perceived performance. Until and unless teams have better data about their performance, the global baseline budget should be enforced.

TL;DR: A lot has changed since 2017 when we last estimated a global baseline resource per-page resource budget of 130-170KiB. 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.

These strange questions came to the fore back in 2014 when Netflix was switching services from CentOS Linux to Ubuntu, and I helped debug several weird performance issues including one I'll describe here. A quick check of basic performance statistics showed over 30% higher CPU consumption. How would you _time_ time?

TL;DR: performance budgets are an essential but under-appreciated part of product success and team health. — Alex Russell (@slightlylate) October 4, 2017. Performance budgets are set early in the life of the project. Budgets are scaled to a benchmark network & device. Maybe "ambush by JS"?

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.

Back in 2017 the engineering team at Facebook had a problem. While ultimately this new system should be able to take advantage of the latest advances in consensus for improved performance, that’s not realistic given a 6-9 month in-production target. Every little helps! What Facebook needed, literally, was a plan to throw one away.

For many years, I explicitly advised people not to run their SQL Server workloads on AMD hardware because of the much lower single-threaded CPU performance and consequently higher SQL Server core license costs. This has led to a very noticeable reduction in generational performance increases since Broadwell-EP, as shown in Figure 1.
