サイトに適したリソース配置とasync/defer完全マスター – レンダリング優先のグッド・プラクティス | ゆっくりと…
タイトル、少し変えました 😉 。 第1部「サイト高速化の「戦略」と「戦術」- GradeAのその先へ」では、YSlow や PageSpeed がアドバイスする Tips のうち、HTTP リクエストの削減を優先すべしという「戦略」の話をしました。 また css や js を束ねて結合し、HTTP リクエストを削減する時の「戦術」の話もしました。 今回は、「サイトの特性に適したリソースの配置を行う」ために、「束ねたリソースをドキュメント中にどう配置するのが適切か」を見い出したいと思います。またそのポイントとなるブラウザの基本的な挙動についても言及します。 ブラウザごとの挙動が確かめられる、実験サイト contentloaded.com を立ち上げたので、以下、同サイトから幾つかの例を引きながら話を進めたいと思います。 リソース配置を決める戦術 基本的な戦術 第1部 では、css や js
User timing API | Articles | web.dev
High performance web applications are crucial to a great user experience. As web applications become more and more complex, understanding performance impact is vital to creating a compelling experience. Over the past few years, a number of different APIs have appeared in the browser to help analyse performance of the network, load times, etc. but these don’t necessarily give fine-grained detail wi
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

How To Write Fast, Memory-Efficient JavaScript — Smashing Magazine
There are many common pitfalls when it comes to writing memory-efficient and fast code. In this article we’re going to explore some test-proven approaches for writing code that performs better. JavaScript engines such as Google’s V8 (Chrome, Node) are specifically designed for the fast execution of large JavaScript applications. As you develop, if you care about memory usage and performance, you s
Performance of Javascript (Binary) Byte Arrays in Modern Browsers
Performance of Javascript (Binary) Byte Arrays in Modern Browsers A little over a year ago I started the noVNC project, an HTML5 VNC client. noVNC does a lot of processing of binary byte array data and so array performance is a large predictor of overall noVNC performance. I had high hopes that one of the new binary byte array data types accessible to Javascript (in modern browsers) would give noV
