In this article, we will review what third-party resource requests are, consider how impactful they can be to the user experience, and discuss common optimization strategies to reduce the impact on the user experience. In many cases, they can be super convenient to add or remove without having to push code changes to the site.

A learning organization, disaster recovery testing, game days, and chaos engineering tools are all important components of a continuously resilient system. Next you record what effect you expect your mitigation strategy to have, which should drop its RPN and then let you focus on the new highest RPN, until there aren’t any high values left.

Minification removes unnecessary spaces and characters, but uglification actually ‘mangles’ the code to be shorter. The tell-tale sign is that the code contains short, machine-generated variable names rather than untouched source code. But I suspect a lot of it is tracking code and advertising setup.

Who owns this code? Some begin an unproductive blame game, accusing tech leads of incompetence, or worse. Moving traffic from one histogram bucket to another becomes a measure of success, and teams at Level 3 begin to understand their distributions are nonparametric , and they adopt more appropriate comparisons in response.

And suddenly, before you know it, the code base gets a little bit overweight and fragmented , third-party scripts have to load just a little bit earlier, and shiny new dynamic content finds its way into the DOM through the backdoors of fourth-party scripts and their uninvited guests. This is where we started. Large preview ).

Have we optimized enough with tree-shaking, scope hoisting, code-splitting, and all the fancy loading patterns with intersection observer, progressive hydration, clients hints, HTTP/3, service workers and — oh my — edge workers? Performance Budgets, Pragmatically shows you a strategy to achieve that. Large preview ).

Is it worth exploring tree-shaking, scope hoisting, code-splitting, and all the fancy loading patterns with intersection observer, server push, clients hints, HTTP/2, service workers and — oh my — edge workers? It’s much easier to reach performance goals when the code base is fresh or is just being refactored.

Is it worth exploring tree-shaking, scope hoisting, code-splitting, and all the fancy loading patterns with intersection observer, server push, clients hints, HTTP/2, service workers and — oh my — edge workers? How do we actually know where we stand in terms of performance, and what our performance bottlenecks exactly are?
