Oh my, I love you, @SpeedCurve ❤️

Set a client up with @SpeedCurve and we’re custom-capturing some more high-fidelity Network and Device information. When people say ‘You users could be in the middle of a field!’, most of theirs actually are.

A must-read on web performance & conversion rates from the @SpeedCurve team:
🧊 The longer the page froze, the more conversions tanked.
📉 At 4s+, it plateaued - most users likely closed the tab entirely.
Speed isn’t just UX, it can make or break business.

I’m toying around with @SpeedCurve’s Compare feature. @csswizardry.com readers who are served faster pages are far more likely to paginate to a new article and far less likely to bounce.

The gulf between localhost, synthetic testing, and real users is pretty hard to reconcile. But, @__treo for Core Web Vitals only (real users), and @SpeedCurve for everything (synthetic and real users). Also, this deck might help: speakerdeck.com/csswizardry/…
The User Happiness score aggregates a number of key #webperf and #ux metrics to give you an at-a-glance understanding of how many "happy" versus "unhappy" page views your site delivered.
Here's how it's calculated: support.speedcurve.com/docs/…
Real User Monitoring (RUM) is a game changer when understanding how real people experience your website.
This screenshot from @SpeedCurve shows just how valuable RUM can be — it highlights real-time metrics like:
✅ Largest Contentful Paint
✅ Interaction to Next Paint
✅ Cumulative Layout Shift
…and how they directly impact user happiness.
Notice that only 43% of users were truly happy with the performance. There’s a huge opportunity for improvement, potentially boosting conversion rates and user retention.
Tools like SpeedCurve help us go beyond lab data and dive into what’s happening in the wild.
Better performance = better UX = better business
Let me know if you're using RUM in your performance workflow?

ALT Screenshot of the SpeedCurve RUM (Real User Monitoring) tool showing real-time web performance metrics. At the top, a “User Happiness” indicator is divided into three colors: green for “Happy” (43%), yellow for “Okay” (44%), and red for “Unhappy” (13%). Below are three line charts with key performance metrics: 1. Largest Contentful Paint (LCP): Average of 3.03 seconds, with varying peaks between 5:10 pm and 5:35 pm. 2. Interaction to Next Paint (INP): Average of 324 milliseconds, with fluctuations shown in red and orange throughout the same time period. 3. Cumulative Layout Shift (CLS): Constant value of 0, with green charts showing intermittent spikes but no final accumulation. Each chart includes a trend line overlaid on vertical bars representing the distribution over time.

I talk with a LOT of companies. What do the fastest sites have in common? They use performance budgets to prevent regressions and deliver a consistently fast #UX.
What's a #webperf budget? This guide covers everything you need to know to get started.

It's not enough to focus on Core Web Vitals numbers. You need to drill down & find the root causes of poor #webperf & #UX.

Is TTFB a hot new metric? No.
Is it a key #webperf metric for tracking responsiveness? YES! Slow TTFB virtually guarantees your site will deliver a poor #UX. Bonus: It's widely available across browsers!
@tkadlec explains how to diagnose TTFB issues...
