"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!
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...
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

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!

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...
How often do you find yourself in this position though? Where LCP is not actually what most people would pick as LCP when looking at a page. When LCP is unintuitive and complex it breeds disinterest.
A graphic showing the following list of bulleted text: CrUX is not the same as RUM. CrUX is only collected from Chrome browsers, while RUM looks gathers data from all browsers. (This is a huge factor.) Sample sizes are probably different. Data aggregation is probably different. CrUX data is rolled up monthly, while your RUM time period can vary depending on how you're looking at your data. You may be comparing substantially different dimensions/cohorts CrUX only segments a site by origin, while RUM allows for deeper segmentation.
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.

A well articulated debug Harry, but it distresses me that this is where we at as a perf community. Has LCP really made it easier for devs to improve user experience? The detailed caveats and nuances you had to go through to understand LCP are beyond what we should consider a “good” metric.
Around 12-15 days. We’re taking it pretty easy so aiming for 15 days. 100km per day average.
It’s an antique now! Should really be on display somewhere.

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. 😢
Web font subsetting with Unicode ranges is such an awesome and under appreciated feature.
We done this on SpeedCurve for ages. Works great. Unicode ranges don’t get enough attention. Super powerful 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.
CWV would be great as iOS is a huge blindspot for a lot of people and is a significant amount of traffic. Even better would be element/container timing. Apple values great user experience yet there’s very little in WebKit to help us measure the performance of what user actually see.
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)

4 panels of images. Top left is a dude hugging a dog, captioned "Developers". The dog is captioned "Developer Experience". There's a sad looking cat in the background. In the third panel there's a zoomed shot of the cat, labelled "Users trying to load the website you built"
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.

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.
