SpeedCurve has been acquired by @embracemobile! We’re combining forces to connect performance, reliability, and user experience across web and mobile apps.

Our founder @MarkZeman shares how our 12-year journey led us here: https://t.co/jDVDd8nbcl

@Cloudflare @SpeedCurve 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.

@glenathan @csswizardry @__treo Thanks for the shout-out, Harry! 🥰

Hi Glen! We'd love to have you try our synthetic and RUM. You can start your trial here: https://t.co/y0acyVPJgP

If you have any questions, fire us a note at [email protected]. We'd be more than happy to do a Q&A/walkthrough with you!

[Harry Roberts @csswizardry]

@glenathan 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: https://t.co/A4JcMsISWR

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: https://t.co/wcdorGxLqX

[Joan León 🏞️⚡️ @nucliweb]

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?

@Shpigford @JonathanDrake @tameverts Thanks for the kind words, Jonathan! 😊

If the holiday season has crept up on you, fear not! There's still a lot you can do to keep your site fast – and your users happy – through the holidays and beyond. @cliffcrocker shares 10 things you can do before your holiday code freeze.

[Tammy Everts @tameverts]

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.

[SpeedCurve @SpeedCurve]

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

🟦 Identify problem pages
🟨 Pinpoint problem page elements
🟩 Get full diagnostics so you know HOW to fix issues

[Tammy Everts @tameverts]

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...
