Making complex web apps faster
On the web, speed is everything. The responsiveness of your browser, the time it takes for a web app to appear, and how quickly that app handles user interactions all directly impact your experience as a web user. At Microsoft, we care deeply about improving web performance, and we’re making progress on it from several directions: Within the browser itself, by making Edge faster and more responsiv
Accelerate Next.js in Kubernetes
That's 93.6% faster median latency and near-perfect reliability compared to the standard approaches for scaling Node.js applications. These results come from production-grade benchmarks on real Next.js applications running on Kubernetes, comparing three common deployment strategies with identical total CPU resources (6 CPUs each). All configurations were tested under the same sustained load patter

I Built the Same App 10 Times: Evaluating Frameworks for Mobile Performance | Loren Stewart
Performance context: All frameworks tested achieve excellent Lighthouse scores (100) with similar First Contentful Paint times. Since performance is essentially identical, bundle size is what differentiates these frameworks for mobile users. The 6.1x range matters for data usage, parse time, and battery consumption. Field data validation: The Chrome User Experience Report (CrUX) provides real-worl

Tailwind vs Linaria: Performance Investigation
Investigating performance of Tailwind vs Linaria frameworks, with a focus on initial load and interaction performance. What's your position on Tailwind? Love or hate? Seems to be no in-between for that one. Even if you've never used it, you probably heard of it by now. It's the second most popular UI framework out there after all, and the source of lots of hype in certain corners of the internet.
