HTML, CSS, images, and fonts can all be parsed and run at near wire speeds on low-end hardware, but JavaScript is at least three times more expensive, byte-for-byte. Since 2010, volumes have been on a slow downward glide path , shrinking from ~350MM per year in a decade ago to ~260MM in 2018.

Looking at sustained single-core bandwidth for a kernel composed of 100% reads, the trends for a large set of high-end AMD and Intel processors are shown in the figure below: So from 2010 to 2023, the sustainable single-core bandwidth increased by about 2x on Intel processors and about 5x on AMD processors. Details in the next blog entry.)
