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.

Eight years at SpeedCurve! What the WHAT?!?

On the eve of my eighth (!!!) anniversary as a SpeedCurver, I wrote up this ode to the biggest little company I've ever had the privilege to be part of.

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

Single-page apps have unique #webperf challenges. Here are some common performance issues with SPAs and three things you can (and should) do to optimize for them.

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.

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...

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.

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.

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

Stoyan Stefanov @stoyan.me · Nov 25

Say hello to `inverse-subset`! The idea is from a conversation with @andydavies.me at #perfnow. When you have a complete font and a subset e.g. Latin, generate another subset consisting of everything not in the original subset. E.g. all characters that are NOT Latin. npmjs.com/package/inverse-subset

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.

WebPerfWG @webperfwg.org · Nov 22

In our meeting yesterday, we decided to adopt Element Timing (and the followup Container Timing work) into the working group. CfC coming up!!

We also discussed some upcoming improvements to the crash reporting API (still in incubation).

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"
