GitHub - axemclion/browser-perf: Performance Metrics for Web Browsers
Is a NodeJS based tool For measuring browser performance metrics (like frame rates, expensive layouts, paints, styles, etc.) For Web pages, Cordova/Phonegap and other Hybrid applications. Metrics are measured while mimicking real user interactions - clicking buttons, typing content, etc. Tool collects the metrics from sources like about:tracing, Chrome Devtools timeline, IE UI Responsiveness tab,
Writing Fast JavaScript For Games & Interactive Applications
Recent versions of JavaScript engines are designed to execute large bodies of code very fast but if you don't know how JavaScript engines work internally you could easily degrade your application's performance. It's specially true for games that need every drop of performance they can get. In this article I will try to explain some common optimization methods for JavaScript code that I picked up d
GitHub - theironcook/Kojak: A Simple JavaScript Performance Profiler
##Kojak: A simple JavaScript performance profiler ####What is Kojak? Kojak is a simple utility that can help you figure out which of your JavaScript functions are running too slow. It tracks when your functions are called, how often they are called, how much time they are taking, how the functions were called. It can also track your ajax calls and help figure out how fast they are. (Kojak was a tv
StrongLoop - What Makes Node.js Faster Than Java?
What Makes Node.js Faster Than Java? by Issac Roth Jan 30, 2014 / Community Every few weeks someone posts a Java vs Node benchmark, like PayPal’s or Joey Whelan’s. As one of maintainers of Node core and contributors to many npm modules, StrongLoop is happy to see Node winning lately. Everyone knows benchmarks are a specific measurement and don’t account for all cases. Sometimes Java is faster. Som
The Future of JavaScript MVC Frameworks
often devs still approach performance of JS code as if they are riding a horse cart but the horse had long been replaced with fusion reactor — Vyacheslav Egorov (@mraleph) December 13, 2013 We’ve known this for some time over here in the ClojureScript corner of the world - all of our collections are immutable and modeled directly on the original Clojure versions written in Java. Modern JavaScript

60fps scrolling using pointer-events: none
60fps scrolling using pointer-events: none Paul Lewis did an interesting article a while back about avoiding unnecessary paints through disabling hover effects as the user scrolls, which is a great approach. The down side being managing all your hover states through a parent class. UPDATE: I’ve done a follow up article which demonstrates a more robust technique. That approach doesn’t scale well an
JetStream
JetStream 3.0 is a JavaScript and WebAssembly benchmark suite focused on the most advanced web applications. It rewards browsers that start up quickly, execute code quickly, and run smoothly. For more information, read the in-depth analysis. Bigger scores are better. Non-standard Parameters JetStream ran with non-standard parameters. The results are likely not comparable to default runs.

Visualising JavaScript Processing Over Time With DevTools Flame Charts
Visualising JavaScript Processing Over Time With DevTools Flame Charts In this quick video, I walk through how to effectively use DevTools Flame Charts for visually representing your app's JavaScript processing over time. This can be useful if you're concerned it may be suffering from particularly long function executions and you want to dive into them further. Flame Charts compliment the existing
How Bad is DOM Interaction - Really?
Lots of us frontend developers seem to be increasingly concerned with interacting with the DOM lately, during a time when JavaScript engines and browser rendering performance has been faster than ever! In this article I will try to douse a few myths about DOM interaction in foam, whilst giving a few little performance tips to make sure your apps run super fast when you're interacting with the DOM.
Enough with the JavaScript already!

It highlights various strategies, including server-side rendering and progressive enhancement, to improve user experience while addressing issues like excessive Jav
Use forensics and detective work to solve JavaScript performance mysteries | Articles | web.dev
Introduction In recent years, web applications have been sped up considerably. Many applications now run fast enough that I've heard some developers wonder aloud "is the web fast enough?". For some applications it may be, but, for the developers working on high performance applications, we know it is not fast enough. Despite the amazing advances in JavaScript virtual machine technology, a recent s

ecmascript generators from a performance perspective — wingolog
It's been really gratifying to see the recent interest in ES6 generators in V8. I'm still a Schemer at heart, but one thing all language communities should learn from JS is its enthusiasm and sense of joyful play. One can't spend much time around folks like James Long or Domenic Denicola without feeling the urge to go out and build something fun. perfie perf perf perf But this is a blog about narg
