Web performance – Weekend must-read articles #26

web performance

This is our collection of must-read articles for the weekend.  There’s something about mobile web, front-end optimization, CDNs, JavaScript, and more.

Every week we bring you a collection of links to places on the web that we find particularly newsworthy, interesting, entertaining, and topical. We try to focus on some particular area or topic each week, but in general we will cover Internet, web development, networking, performance, security, and other geeky topics.

This week’s suggested reading

Rich JavaScript Applications – the Seven Frameworks

For many web developers, it’s now taken for granted that such client-side frameworks are the way to build rich web apps. If you’re not using one, you’re either not building an application, or you’re just missing out.
There’s lots of consensus among the main frameworks about how to do it (Model-View-* architecture, declarative bindings, etc. — details below), so to some extent you get similar benefits whichever you choose. Some major philosophical differences remain, especially the big split between frameworks and libraries. Your choice will deeply influence your architecture. The conference itself was stylish and upbeat, with a lot of socialising and conversations across different technology groups. I’d like to see more like this.

Mobile Web Performance

Measure and optimize with mod_pagespeed experiments

Making your site fast shouldn’t require lots of manual optimization. With mod_pagespeed, an open-source Apache module, you can automatically apply web performance optimization best practices like cache extension, image optimization, and css inlining to speed up your site without a lot of hassle. As of version, mod_pagespeed now supports A/B tests integrated with Google Analytics, allowing you to measure how much it speeds up your site on live traffic and experimentally determine the best settings.

Front-End Optimization Architecture – Decisions and Implications (Part 2)

It’s pretty clear you’ll optimize local resources, as those are readily available. It’s not clear, however, whether you’ll optimize remote resources. In order to optimize remote resources you must be able to “see” them during analysis. This requires actively requesting them, unlike local resources, which can be passively “seen” as they get delivered. Such active requests are hard to do if you’re analyzing locally, and are even harder if you’re doing inline analysis.

Turbocharging web sites with new PageSpeed Service optimizations

We are constantly working on new optimizations (rewriters) that can make pages load even faster. Along these lines, we are introducing a new rewriter called “Cache and Prioritize Visible Content”. This rewriter enables users to start interacting with the web page and consuming the content much sooner. It accomplishes this by optimizing the page as a whole using the following web page-aware techniques and with minimal configuration needed.

State Of The CDN: More Traffic, Stable Prices, More Products, Profits – Not So Much

CDNs (content delivery networks) are the secret shadow super powers behind the web and Dan Rayburn at streamingmedia.com is the go to investigative reporter for quality information on CDNs. Every year Dan has a Content Delivery Summit on all things CDN and those videos are now available. Dan also gives a kind of state of the industry talk where he does something wonderful, he gives real numbers and prices.

Interview with Alan Kay

The pioneer of object-orientation, co-designer of Smalltalk, and UI luminary opines on programming, browsers, objects, the illusion of patterns, and how Socrates could still make it to heaven.
