2015-2020: Overhead As part of production rollout I did many performance overhead tests, which I've described publicly before: The overhead of adding frame pointers to everything (libc and Java) was usually less than 1%, with one exception of 10%. We may get there with future technologies I'll cover later.

If you have been paying attention to the technology press over the past 12-18 months, you may have noticed a rather large number of negative stories about Intel's processor business. This made it easier for database professionals to make the case for a hardware upgrade, and made the typical upgrade more worthwhile.

Devices and networks have evolved too: Alex Russell @slightlylate An update on mobile CPUs and the Performance Inequality Gap: Mid-tier Android devices (~$300) now get the single-core performance of a 2014 iPhone and the multi-core perf of a 2015 iPhone. Hardware Past As Performance Prologue. Mind The Gap. A 2021 Global Baseline.

JavaScript-Heavy # Since at least 2015, building JavaScript-first websites has been a predictably terrible idea, yet most of the sites I trace on a daily basis remain mired in script. [1] Having provisioned more than adequately in the 4G era, new technology isn't having the same impact from pent-up demand.

On the other hand, we have hardware constraints on memory and CPU due to JavaScript parsing times (we’ll talk about them in detail later). In real-life world, most products aren’t even close: an median bundle size today is around 417KB , which is up 42% compared to early 2015.
