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. Many critiques are possible, both of the target (five seconds for first load), the sample population (worldwide internet users), and of the methodology (informed reckons).

I recently profiled a page on a Pixel 2 (released in 2017), and an Alcatel 1x (released in 2018). My home internet connection gives me somewhere around 3 Mbps down. Hardware gets better, sure. The two devices represent very different ends of the spectrum. It seems blazingly fast compared to the 0.42 It makes sense.

As a Xen guest, this profile was gathered using perf(1) and the kernel's software cpu-clock soft interrupts, not the hardware NMI. Colleagues/Internet I love using [Linux performance tools]. But I also love solving issues quickly, and sometimes that means just asking colleagues or searching the Internet.

Instead of focusing on hardware and infrastructure first, technical teams should first ensure that they first have visibility on the thing that drives the business: their customer experience. Paul Calvano has an awesome post using HTTP archive data to detail the prevalence of third party content on the internet.

In almost every area, Apple's low-quality implementation of features WebKit already supports requires workarounds not necessary for Firefox (Gecko) or Chrome/Edge/Brave/Samsung Internet (Blink). WebGL 2 launched for other platforms on Chrome and Firefox in 2017. is access to hardware devices. Converging Views. Shape Detection.

Hardware installation was a lot of work but not too frustrating, I did it in about two days over the holidays. Eventually I discovered a new option called Noon ( noonhome.com )?—?they

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). Gatsby.js (React), Preact CLI , and PWA Starter Kit provide reasonable defaults for fast loading out of the box on average mobile hardware. Image credit: Addy Osmani ) ( Large preview ).
