Links on Performance I

This post summarizes several insightful articles on web performance optimization. The common thread? There's a wealth of untapped potential for improvement.

Manuel Matuzovic's article, "Why 543 KB keep me up at night," highlights a surprising culprit behind bloated page sizes: JavaScript. He also reveals Google's recommended ideal DOM structure, emphasizing limits on node count, depth, and child nodes per parent.

Another article, "Performant front-end architecture," discusses bundle splitting in client-side JavaScript applications. While increasing requests, parallel loading mitigates the issue, especially with HTTP/2. The article stresses code-splitting as a top priority for performance gains in these applications.

Jeremy Keith's "Telling the story of performance" champions WebPageTest as a powerful tool, not just for measurement, but also for visually demonstrating performance differences to clients through side-by-side loading videos.

Finally, CP Clermont's "The Impact of Web Performance" quantifies the business benefits of improved performance. The study reveals a significant revenue increase—over 3x on mobile and nearly 6x on desktop—for users experiencing faster load times. This underscores the critical link between performance and profitability.
