Improving Smashing Magazine’s Performance: A Case Study

Today Smashing Magazine turns eight years old. Eight years is a long time on the web, yet for us it really doesn't feel like a long journey at all. Things have changed, evolved and moved on, and we gratefully take on new challenges one at a time. To mark this special little day, we’d love to share a few things that we’ve learned over the last year about the performance challenges of this very website and about the work we’ve done recently. If you want to craft a fast responsive website, you might find a few interesting nuggets worth considering. – Ed.

Improving Smashing Magazine's Performance: A Case Study

Improvement is a matter of steady, ongoing iteration. When we redesigned Smashing Magazine back in 2012, our main goal was to establish trustworthy branding that would reflect the ambitious editorial direction of the magazine. We did that primarily by focusing on crafting a delightful reading experience. Over the years, our focus hasn't changed a bit; however, that very asset that helped to establish our branding turned into a major performance bottleneck.

You May Be Losing Users If Responsive Web Design Is Your Only Mobile Strategy

You resize the browser and a smile creeps over your face. You’re happy: You think you are now mobile-friendly, that you have achieved your goals for the website. Let me be a bit forward before getting into the discussion: You are losing users and probably money if responsive web design is your entire goal and your only solution for mobile. The good news is that you can do it right.

You May Be Losing Users If Responsive Web Design Is Your Only Mobile Strategy

In this article, we’ll cover the relationship between the mobile web and responsive design, starting with how to apply responsive design intelligently, why performance is so important in mobile, why responsive design should not be your website’s goal, and ending with the performance issues of the technique to help us understand the problem.

Streamlining Mobile Interactions

The mobile web is a harsh environment: mobile processors are slower than their desktop counterparts; network connectivity is flaky; bandwidth is low; latency is high; and touchscreen keyboards are slow. The best mobile web applications are the ones that excel at handling these challenges.

Streamlining Mobile Interactions

In this article, we'll look at how to identify the tasks your users want to accomplish on a mobile device, memorize as much as you can about your users’ situation, presume that your users’ actions will succeed (and get them to their next task) and also how to predict your users’ next actions, and prepare accordingly.

Cache Invalidation Strategies With Varnish Cache

Phil Karlton once said, "There are only two hard things in Computer Science: cache invalidation and naming things." This article is about the harder of these two: cache invalidation. It’s directed at readers who already work with Varnish Cache. To learn more about it, you’ll find background information in “Speed Up Your Mobile Website With Varnish.”

10 microseconds (or 250 milliseconds): That’s the difference between delivering a cache hit and delivering a cache miss. How often you get the latter will depend on the efficiency of the cache — this is known as the “hit rate.” A cache miss depends on two factors: the volume of traffic and the average time to live (TTL), which is a number indicating how long the cache is allowed to keep an object. As system administrators and developers, we can’t do much about the traffic, but we can influence the TTL.

One Solution To Responsive Images

Responsive images have been, and are, one of the hardest problems in responsive Web design right now. Until browser vendors have a native solution, we have to think on the fly and come up with our own solutions. “Retina” images are especially a challenge because if you have sized your layout with ems or percentages (as you should!), then you cannot be sure of the exact pixel dimensions of each image being displayed.

One Solution To Responsive Images

In this article, we’ll look at one solution to the problem that we implemented on our portfolio website at Etch, where you can see an early working version in the wild.

Speed Up Your Mobile Website With Varnish

Imagine that you have just written a post on your blog, tweeted about it and watched it get retweeted by some popular Twitter users, sending hundreds of people to your blog at once. Your excitement at seeing so many visitors talk about your post turns to dismay as they start to tweet that your website is down — a database connection error is shown.

Speed Up Your Mobile Website With Varnish

Or perhaps you have been working hard to generate interest in your startup. One day, out of the blue, a celebrity tweets about how much they love your product. The person’s followers all seem to click at once, and many of them find that the domain isn’t responding, or when they try to sign up for the trial, the page times out.

Addressing The Responsive Images Performance Problem: A Case Study

Five-inch mobile devices are on the market that have the same screen resolution as 50-inch TVs. We have users with unlimited high-speed broadband as well as users who pay money for each megabyte transferred. Responsive design for images is about optimizing the process of serving images to users.

Addressing The Responsive Images Performance Problem: A Case Study

In this article, we will share our responsive image technique, the “padding-bottom” technique, which we researched and implemented on the mobile version of the Swedish news website Aftonbladet.
