Real-world data in PageSpeed Insights- Google Developers Blog
Share Facebook Twitter LinkedIn Mail Posted by Mushan Yang and Xiangyu Luo, Software Engineers PageSpeed Insights provides information about how well a page adheres to a set of best practices. In the past, these recommendations were presented without the context of how fast the page performed in the real world, which made it hard to understand when it was appropriate to apply these optimizations.
How to print integers really fast (with Open Source AppNexus code!) - Paul Khuong: some Lisp
Back in 2014, AppNexus needed a faster way to convert machine integers to strings. It’s a stupid problem to have–just use a binary format–but it’s surprisingly common. Maybe a project can only grow large enough for serialisation speed to be an issue if it first disregards some trivial concerns. I can finally share our solution: after failing to nicely package our internal support code for years, w

Comparing Browser Page Load Time: An Introduction to Methodology On blog.mozilla.org, we shared results of a speed comparison study to show how fast Firefox Quantum with Tracking Protection enabled is compared to other browsers. While the blog post there focuses on the results and the speed benefits that Tracking Protection can deliver to users even outside of Private Browsing, we also wanted to s
The Cost Of JavaScript
As we build sites more heavily reliant on JavaScript, we sometimes pay for what we send down in ways that we can’t always easily see. In this post, I’ll cover why a little discipline can help if you’d like your site to load & be interactive quickly on mobile devices. tl;dr: less code = less parse/compile + less transfer + less to decompress NetworkWhen most developers think about the cost of JavaS

The Front-End Performance Challenge: Make Your Site Blazingly Fast And Win Some Smashing Prizes — Smashing Magazine
Not too long ago, front-end performance was a mere afterthought. Something that was postponed to the end of a project and that didn’t go much beyond minification, asset optimization, and maybe a few adjustments on the server’s config file. But things have changed. Not too long ago, front-end performance was a mere afterthought. Something that was postponed to the end of a project and that didn’t g
Building the DOM faster: speculative parsing, async, defer and preload – Mozilla Hacks - the Web developer blog
Building the DOM faster: speculative parsing, async, defer and preload In 2017, the toolbox for making sure your web page loads fast includes everything from minification and asset optimization to caching, CDNs, code splitting and tree shaking. However, you can get big performance boosts with just a few keywords and mindful code structuring, even if you’re not yet familiar with the concepts above

Tracking Page Weight Over Time
As of July 2017, the “average†page weight is 3MB. @Tammy wrote an excellent blog post about HTTP Archive page stats and trends. Last year @igrigorik published an analysis on page weight using CDF plots. And of course, we can view the trends over time on the HTTP Archive trends page. Since this is all based on HTTP Archive data, I thought I’d start a thread here to continue the discussion on how t
Making the web smoother with independent rendering
Independent rendering allows the browser to selectively offload graphics processing to an additional CPU thread, so they can be rendered with minimal impact to the user interface thread and the overall visible performance characteristics page, such as silk-smooth scrolling, responsive interactions, and fluid animations. This technique was pioneered in Internet Explorer 11, and is key to providing

SpeedCurve | The average web page is 3MB. How much should we care?
The average web page is 3MB. How much should we care? See our more recent page growth posts: What is page bloat? And how is it hurting your business, search rank, and users? (July 2023) 10 years of page bloat: What have we learned? (March 2022) A couple of month ago, someone asked if I'd written a page bloat update recently. The answer was no. I've written a lot of posts about page bloat, starting
