Loving the shift away from bloated client-side JavaScript. With RUM tools offering better visibility into the impact of JS, the DX vs. UX trade-off is becoming harder to ignore. Any UX focused changes in your stack making it to production? Did your numbers improve? www.speedcurve.com/blog/long-an...

"How fast is fast enough?" If you've ever asked this question, then you might want to join tomorrow's SPDY STREAM! Henri and I will be chatting about how to answer that question, among other things. See you there at 10am PDT / 1pm EDT!

I want all my web performance metrics described with baking analogies. Who knew that cake had "Frontend" time. Although that would mean that a cake's Time To First Bite (Backend) would come after Frontend!

A company should exist to enrich and support us as individuals. Not for us to enrich it. It’s nothing without its fabulous people.

Ever wondered why your business and engagement metrics didn't improve after you sped up your pages? You need correlation charts. 👍 Validate your #webperf & #UX metrics 👍 Identify your site's "performance plateau" 👍 Spot performance-blocking trends on your pages www.speedcurve.com/blog/site-sp...

There is also a 4th, slightly more controversial optimisation trick for SPAs as well.

Love them or not, you’ve got to be up to speed on Core Web Vitals.

Hey gang! This month's performance hero is a man who needs no introduction. (I've always wanted to say that.) Join us in celebrating the OG #webperf hero: @patmeenan.com! www.speedcurve.com/blog/web-per...

Would love to see the Web Almanac talk more about Safari's lack of perf metrics next year. There's a huge chunk of traffic not being looked at or analysed. There's zero mention of this missing context. almanac.httparchive.org/en/2024/perf...

I just had a good chat with a @speedcurve.com customer who wanted to know why their CrUX numbers didn't match their RUM numbers. It was a good reminder that even experienced #webperf / #ux folks might not realize that CrUX isn't full RUM. Helpful explainer: support.speedcurve.com/docs/speedcu...

Super excited to see this bike packing build come together. Will be riding the Sounds to Sounds in March. www.touraotearoa.nz/p/sound-to-s...

As a dyslexic, not being able to edit posts on BlueSky is a bit rough. 😢

I love my new @speedcurve.com #perfhero sticker 🥰

Web font subsetting with Unicode ranges is such an awesome and under appreciated feature.

Amazing to see Element/Container Timing gathering steam. These are fundamental for truly connecting web performance and user experience. Huge thank you to @jasew.bsky.social and @yoav.ws for pushing these along.

Would you want core web vitals In Safari? Can you help me understand how you would use them and why numbers in one browser isn’t enough? (These may sound like silly questions, but I’d love to understand *your* specific context and use cases)

Hi, we're so happy to be here! Meet our small but mighty team: www.speedcurve.com/about/ Andy Biggs Cliff Crocker @cliffcrocker.bsky.social Andy Davies @andydavies.me Tammy Everts @tammyeverts.bsky.social Elena Kay Steve Souders Joseph Wynn @josephwynn.bsky.social Mark Zeman @markzeman.bsky.social

YES! Core Web Vitals are an awesome starting point, but they’re not the final destination. @tkadlec.bsky.social at #PerfNow

Thanks for the notes Stuart! I wasn’t able to make it this year. PPK puts an awesome conference together.

Per @slightlyoff.bsky.social’s #perfnow talk… GOV.UK publishes great performance case studies on their tech blog. This is one of them. technology.blog.gov.uk/2020/07/02/s...

Took 2 mins at #PerfNow to talk about the RUM Community Group in W3C for anyone doing RUM. It's free and easy to join if you're interested! www.w3.org/community/ru...

Very inspired by stories from participants of the Women Coding Community at #halfstackconf. Lots of cross-training and activating. A program that offers resumé clinics, interview coaching, coding clubs, career clubs, speaking clubs, mentoring programs, and much more. womencodingcommunity.com

🫵 I’m looking to add a Flagship client for 2025. You’re an ambitious organisation with a long-term, strategic outlook. You have the desire and capability to be best-in-class, you just need a little guidance. Is that you? We should talk.

#perfnow was super invigorating. Here are my Pushing Pixels slides loaded with Midjourney goodness. See you all next year. noti.st/zeman/U2Xtyt...
