HTTP/3 is Fast

HTTP/3 is here, and it’s a big deal for web performance. See just how much faster it makes websites! Wait, wait, wait, what happened to HTTP/2? Wasn’t that all the rage only a few short years ago? It sure was, but there were some problems. To address them, there’s a new version of the venerable protocol working its way through the standards track. Ok, but does HTTP/3 actually make things faster? It sure does, and we’ve got the benchmarks to prove it.

Using HTTP Caching: 2022 Guide

The fastest website is the website that is already loaded, and that’s exactly what we can do with HTTP caching. HTTP caching lets web browsers reuse of previously loaded resources, like pages, images, JavaScript, and CSS. It’s a powerful tool to improve your web performance, but misconfiguration can cause big performance problems. Here’s what you need to know to use HTTP caching without reading hundreds of pages of HTTP Caching Spec.

Synthetic Testing and Real User Monitoring

Synthetic Testing and Real User Monitoring are the most important tools in your performance toolbox. But they do different things and are useful at different times and many developers only spend time mastering one of these tools and only see a part of their performance problems, like trying to hammer in a screw. Let’s look at these tools, what they measure, and when to use them.

Observable Web Applications

Users don’t see your distributed services, cloud architecture, or instrumentation—they only see how the web app is working. Understanding their experience in the client-side is the first step towards understanding the rest of the system. We’ll explore how to make your client-side applications more observable through error tracking, web performance, and usage analytics. With better understanding of real-user experience, you’ll better understand the real behavior of your systems.
