Great article by Geoff Graham in @smashingmag. How to diagnose and fix third-party bottlenecks that slow down your pages and hurt your users' experience:

🔺 What is the "main thread"?
🔺 Spot long tasks & blocking #JS
🔺 Track #CoreWebVitals like INP & TBT
🔺 Optimize scripts

If you're into #webperf and would like to learn how other folks have found their way to our world, @tannerhodges has a really fun podcast called Catching Up. He chats with folks (like @anniesullie @ethangardner @tunetheweb & @viniciusdallacqua) about their performance journeys. Definitely worth a listen!

Video of my talk about the psychology of web performance at Beyond Tellerrand is up! It was so fun to revisit #webperf / #ux first principles and share them with a new audience. Thank you again to @marcthiele and @btconf for the opportunity!

Love this post by @cliff. He does more than explain what Interaction to Next Paint is and how it's measured. He looks at real user data and creates correlation charts that show how INP aligns with actual user behaviour. It's all about the users!

As a user-focused #webperf metric, does Interaction to Next Paint actually correlate to user behaviour? @cliff analyzed RUM data from four different sites and found that overall there's a correlation between INP and conversions.

Every year I revisit the topic of web performance budgets. Here's my updated guide, including:

✅ What are performance budgets?
✅ Why are they a crucial tool in fighting page speed regression?
✅ Best metrics to track
✅ Determining thresholds
✅ Pro tips

Tech companies are often guilty of making huge assumptions about their users' environments, sacrificing #webperf and #UX as a result.

Interesting to see how many tech sites have slow Largest Contentful Paint (LCP) times (as slow as 34 seconds!) on slower mobile connections:

The best time to set up performance budgets was years ago. The next best time is today.

If you're not using budgets to fight page speed regressions, you're missing a vital tool in your #webperf / #ux toolkit. Here's everything you need to get started.

I've been wishing I could work with @tkadlec pretty much since the day I met him more than ten years ago. Sometimes wishes come true, folks!

Performance budgets help with two of the biggest challenges you might face in your daily work life: too little time + too many people touching your pages.

After you set up #webperf budgets, you can relax knowing everything is fine until you get an alert. Problem solved!

Keeping your site fast is a crucial and endless game. Yet it's perilously easy to lose focus and suffer from regressions. In this excellent, detailed, best-practice-filled post, @tkadlec uses the analogy of guardrails (automated testing & alerts) and breadcrumbs (deployment tracking) to make performance more visible throughout the dev process.

"Putting up the appropriate guardrails to protect ourselves from regressions – then pairing that with a trail of breadcrumbs so that we can dive in and quickly identify what the source is when a regression occurs – are essential steps to ensure that when we make our sites fast, they stay that way."

Awesome post by @tkadlec, filled with high-level wisdom and ground-level best practices.

If you're going to #SmashingConf SF later this month, consider doing a 10-minute lightning talk (about #frontend #ux #webperf or #a11y) at the Jam Session. It's a fun way to get speaking experience in a friendly environment at a great event!

My kids and I love LEGO, so I spend a lot of time on the LEGO site during the holidays. So I thought it would be fun to give the site a quick #webperf audit. Here's what I learned, along with some lessons you may want to apply to your own pages.

"Why do I see different numbers for the same metrics in different tools?" I hear this a lot. You need to trust your tools and metrics. This explainer will help.

🟡 Synthetic vs RUM
🟡 Tool A vs Tool B
🟡 Lighthouse in different tools
🟡 RUM vs CrUX

Thanks to all who came to my #p99conf talk about using performance budgets to fight regressions and stay fast! If you want to learn more, I created this guide. It covers:

🟡 How budgets work
🟢 Which metrics to track
🔵 How to determine thresholds
🟣 CI/CD integration

I had such a great time chatting with @grigs on the @cloudfour podcast! Among other things, we demystified Interaction to Next Paint – including what it does and does not measure. (It's a great metric, but it's definitely not one-size-fits-all!)

If your site uses consent popups/banners (and it probably does), this post is a must-read. CMPs create huge web performance challenges, such as:

1. Single point of failure
2. Mask third-party issues
3. Identify wrong LCP element
4. Hurt CLS score
5. Delay INP

If you care about...

🟡 Delivering a fast UX to your users
🟢 Knowing the minute your site speed starts to suffer (including metrics like Core Web Vitals)
🔵 Fixing performance issues FAST

...then you need performance budgets.
