Performance Optimization: Techniques And Strategies

Performance Optimization: Techniques And Strategies

Slow loading times break the user experience of any website — no matter how well crafted it might be. In fact, it only takes three seconds until users lose their interest in a site if they don't get a response immediately. If another site happens to be 250ms faster than yours, then users are more inclined to switch to a competitor’s website in no time. Web fonts, heavy JavaScript, third-party widgets — all of them can sum up to become a real performance bottleneck. Nevertheless, tracking that down does not only improve loading times but also results in a much snappier experience and a higher user engagement.


In this eBook, we’ve compiled an entire selection of front-end and server-side techniques that will help you tackle such bottlenecks. Find out how to speed up existing websites, build high-performance sites (for both mobile and desktop), and prepare them for heavy-load situations. Furthermore, you’ll learn more about how performance improvements and a 97–99 Google PageSpeed score were achieved on Smashing Magazine, as well as how optimization strategies can enhance real-life projects by taking a closer look at Pinterest’s paint performance case study. With the help of this eBook, you’ll notice that it’s high time to dig deeper into your own site and examine it closely. Why don’t you polish it up and make it even better than it already is!

Excerpt from Chapter 1

Improving Smashing Magazine’s Performance: A Case Study — by Vitaly Friedman

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.

How To Speed Up Your WordPress Website — by Marcus Taylor

A few months ago, I ran an experiment to see how much faster I could make one of my websites in less than two hours of work. After installing a handful of WordPress plugins and fixing a few simple errors, I had improved the website’s loading speed from 1.61 seconds to 583 milliseconds. That’s a 70.39% improvement, without having made any visual changes to the website.
