500ms to 1.7ms In React: A Journey And A Checklist
Written by Oren Farhi, Front End Engineer Tech Lead, follow me on This article has been translated: Chinese 1 (by Qlly) Chinese 2 (by Qlly) Korean (by Ykss) I bet the need to tweak perfomance comes in a certain phase of development for every developer, in every app. There are very good resources and articles about how to tweak performance in react and this article is no exception. I thought I will

Announcing Parcel CSS: A new CSS parser, compiler, and minifier written in Rust!
I'm very excited to announce @parcel/css, a new CSS parser, compiler, and minifier written in Rust! Check it out on GitHub, or try a live demo right in your browser. Parcel CSS has significantly better performance than existing tools, while also improving minification quality. In addition to minification, Parcel CSS handles compiling CSS modules, tree shaking, automatically adding and removing ven
Apple's M1 Pro, M1 Max SoCs Investigated: New Performance and Efficiency Heights
Apple's M1 Pro, M1 Max SoCs Investigated: New Performance and Efficiency Heights Last week, Apple had unveiled their new generation MacBook Pro laptop series, a new range of flagship devices that bring with them significant updates to the company’s professional and power-user oriented user-base. The new devices particularly differentiate themselves in that they’re now powered by two new additional

How M1 Macs feel faster than Intel models: it’s about QoS
Last week I showed fascinating screenshots of how M1 Macs can run background processes exclusively on their four ‘efficiency’ cores. I’ve now been digging deeper, and this article is a summary of how Intel and M1 Macs deal with multiple tasks, priorities and resources under macOS, and how that influences our assessment of their speed. Operations and QoS Whether Intel or ARM cores, macOS has to man
Cloudflare Pages is now Generally Available
In December, we announced the beta of Cloudflare Pages: a fast, secure, and free way for frontend developers to build, host, and collaborate on Jamstack sites. It’s been incredible to see what happens when you put a powerful tool in developers’ hands. In just a few months of beta, thousands of developers have deployed over ten thousand projects, reaching millions of people around the world. Today,
JavaScript performance beyond bundle size
23 Feb JavaScript performance beyond bundle size Posted February 23, 2021 by Nolan Lawson in performance, Web. 8 Comments There’s an old story about a drunk trying to find his keys in the streetlight. Why? Well, because that’s where it’s the brightest. It’s a funny story, but also relatable, because as humans we all tend to take the path of least resistance. I think we have the same problem in the
content-visibility: the new CSS property that boosts your rendering performance | Articles | web.dev
The content-visibility property, launching in Chromium 85, might be one of the most impactful new CSS properties for improving page load performance. content-visibility enables the user agent to skip an element's rendering work, including layout and painting, until it is needed. Because rendering is skipped, if a large portion of your content is off-screen, leveraging the content-visibility proper
Comparing HTTP/3 vs. HTTP/2 Performance
We announced support for HTTP/3, the successor to HTTP/2 during Cloudflare’s birthday week last year. Our goal is and has always been to help build a better Internet. Collaborating on standards is a big part of that, and we're very fortunate to do that here. Even though HTTP/3 is still in draft status, we've seen a lot of interest from our users. So far, over 113,000 zones have activated HTTP/3 an
The story of a V8 performance cliff in React · V8
Show navigation Previously, we discussed how JavaScript engines optimize object and array access through the use of Shapes and Inline Caches, and we’ve explored how engines speed up prototype property access in particular. This article describes how V8 chooses optimal in-memory representations for various JavaScript values, and how that impacts the shape machinery — all of which helps explain a re
