We checked the WebPerformance of Nintendo's website before Sunday’s delivery. Everything looks good!
Take a look at the report:

AI had a fever dream about a brand-new Core Web Vital.

I'm not going to call out the tech company blog where I saw this. I'm posting it as a cautionary tale about using ChatGPT to write about subject matter that's outside your wheelhouse.

Woah, they've really out done themselves. The attention to detail. Perfection!

Slow as it ever was.
Slow as it, ever, was?
Slow as it, *ever* was!
Slow as it ever was...

It's got only 900 views after 2y. Let's give 'em some love!

Howdy, everyone! It kinda feels like it's a good time for an updated #introduction, no?

Name's Jason. I'm the fella behind `simian.rodeo`, a place for sad-eyed space cowpokes. Registrations are (kind of) open. I'll explain more here:

Attending a #webperf symposium today.

WebPerformance Report Week #17 is out and today we celebrate a new milestone!
For the first time, we delivered two reports in one day:
Web Performance Report
HTTP Header Security Report
https://webperformancereport.com/
#webperf #corewebvitals #ux #seo #cybersecurity #websecurity

Users will abandon your page if it appears empty and inactive for more than 3 seconds. If they see content rendering or the skeleton of a page loading, you'll buy more time and patience.

Here's how to do it: https://www.speedcurve.com/web-performance-guide/using-critical-css-for-faster-rendering/

New on WebPerformance Report: HTTP Observatory
Check your site's HTTP security headers and get clear, actionable results in your inbox.
Thanks to the @MDN team for their technical guidance.
Because great UX should also be secure.

PerformanceObserver: A virtual...

This month's performance hero is a person after my own heart – someone who is passionate about building a secure, accessible, performant web for EVERYONE, and who always leads with a deep compassion for users. Let's all join in celebrating Alex Russell (@slightlyoff)!

The average person waits almost 6 years to replace their computer.

In other words, A LOT of the people coming to your site could be using a very old device.

Day 10 of 14 days of Web Perf

Once you've fixed your performance, if you're large enough and have a budget, invest in a performance culture.

In my experience and contrary to what a lot of folks in my space might talk about, most companies are too small to dedicate staff toward this. There is a middle ground though...

I recently published my annual dive into the HTTP Archive, focusing on page growth, web performance, and UX: https://www.speedcurve.com/blog/page-bloat-2025/

A common question is "How big SHOULD my pages be?" According to analysis by @slightlyoff, the ideal page should be <1.4 MB with <365 KB coming from JS.

14 Days of Web Perf

To celebrate a follower milestone, I'll be posting web performance tips for the first 14 days in February.

Tune in to this thread each day for a short and sweet nugget (or nougat?) of #webperf knowledge...

BBC World Service have continued to work on a "light" version of their web pages which I mentioned a while back.

There's now a CTA on the Gahuza website (https://www.bbc.com/gahuza) to prompt folks to try the light pages (which can be directly accessed via https://www.bbc.com/gahuza.lite).

The light pages are about 1/5th the file size of the original pages so should be significantly faster, esp. for folks on slower/lossier connections.

Hei all new followers! I’m Arielle and into #DesignSystems, #Design, #WebComponents, #WebPerf, #a11y, #Eleventy, #IndieWeb, #Inclusion, #Typography, #Music and other stuff! There may be (lots?) of random posts as well. Delighted to meet you
