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

GitHub - HigherOrderCO/HVM: A massively parallel, optimal functional runtime in Rust
Higher-order Virtual Machine 2 (HVM2) is a massively parallel Interaction Combinator evaluator. By compiling programs from high-level languages (such as Python and Haskell) to HVM, one can run these languages directly on massively parallel hardware, like GPUs, with near-ideal speedup. HVM2 is the successor to HVM1, a 2022 prototype of this concept. Compared to its predecessor, HVM2 is simpler, fas
Kernel Queue: The Complete Guide On The Most Essential Technology For High-Performance I/O
Kernel Queue: The Complete Guide On The Most Essential Technology For High-Performance I/O When talking about high-performance software we probably think of server software (such as nginx) which processes millions requests from thousands clients in parallel. Surely, what makes server software work so fast is high-end CPU running with huge amount of memory and a very fast network link. But even the
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

The performance effects of too much lazy loading | Articles | web.dev
The performance effects of too much lazy loading Stay organized with collections Save and categorize content based on your preferences. Lazy loading is a technique that defers downloading a resource until it's needed, to conserve data and reduce network contention for critical assets. It became a web standard in 2019 and today loading="lazy" for images is supported by most major browsers. This pag
Compressing JSON: gzip vs zstd – Daniel Lemire's blog
JSON is the de facto standard for exchanging data on the Internet. It is relatively simple text format inspired by JavaScript. I say “relatively simple” because you can read and understand the entire JSON specification in minutes. Though JSON is a concise format, it is also better used over a slow network in compressed mode. Without any effort, you can compress often JSON files by a factor of ten
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
Real-world CSS vs. CSS-in-JS performance comparison
CSS-in-JS has taken a solid place in front-end tooling, and it seems this trend will continue in the near future. Especially in the React world. For example, out of 11492 people who participate in State of CSS survey in 2020 only 14.3% didn’t hear of Styled Components (a dominant CSS-in-JS library). And more than 40% of participants have used the library. I wanted to see an in-depth performance co
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
GPU Benchmarks for Deep Learning | Lambda
GPU Benchmark Methodology To measure the relative effectiveness of GPUs when it comes to training neural networks we’ve chosen training throughput as the measuring stick. Training throughput measures the number of samples (e.g. tokens, images, etc...) processed per second by the GPU. Using throughput instead of Floating Point Operations per Second (FLOPS) brings GPU performance into the realm of t

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
