Video of my talk about the psychology of web performance at Beyond Tellerrand is up! It was so fun to revisit / first principles and share them with a new audience. Thank you again to @marcthiele and @btconf for the opportunity!

It was such a privilege to speak at Beyond Tellerrand last week – alongside an amazing group of people – about a topic dear to my heart: why we crave fast online experiences.

It was so inspiring to see the work and passion that goes on behind the scenes to create such a magical event. And it was wonderful to connect with so many attendees.

Thank you for the wonderful memories! Here is my favourite pic, which sums up how I feel about the passage of time!

One of the things I love about @btconf is getting to learn from such a diverse array of amazing people. Next month I'm excited to learn about:

– Leadership from Dr. Emily Anhalt

– JS from @devdevcharlie

– Walking your own path from @jbrewer

– And more!

As a user-focused metric, does Interaction to Next Paint actually correlate to user behaviour? @cliff analyzed RUM data from four different sites and found that overall there's a correlation between INP and conversions.

If you're into and would like to learn how other folks have found their way to our world, @tannerhodges has a really fun podcast called Catching Up. He chats with folks (like @anniesullie @ethangardner @tunetheweb & @viniciusdallacqua) about their performance journeys. Definitely worth a listen!

Love this post by @cliff. He does more than explain what Interaction to Next Paint is and how it's measured. He looks at real user data and creates correlation charts that show how INP aligns with actual user behaviour. It's all about the users!

An algorithm just reminded me that on this day seven years ago, I got to visit Etsy HQ. It was exactly as awesome as you might imagine.

If you're going to SF later this month, consider doing a 10-minute lightning talk (about or ) at the Jam Session. It's a fun way to get speaking experience in a friendly environment at a great event!

What do companies with fast websites have in common? They all (in my experience) use performance budgets to prevent regressions.

This post has been a long time coming. I did my best to distill all the best practices I've shared at conferences and during countless consultations with companies of all sizes. I hope people find it helpful!

@olorinhenderson Very strange. The site has been working for me all day. Can you let me know what device/browser you're using? And what page you're trying to visit?

tammy,
@tammy@webperf.social avatar

@olorinhenderson Thanks for the details. Just to confirm, is the link still not working for you?

tammy,
@tammy@webperf.social avatar

@olorinhenderson Yeah, I reckon it was something like that. I'll mention it to the team, just to make sure this isn't a more widespread issue. Thanks again for mentioning it!

Wall-E (2008) looks like the bowling machine from The Big Lebowski (1998). Intentional or coincidental?

If you weren't doing what you're doing now, what would be your three most viable alternate career paths?

@brad_frost I had my answers locked and loaded until I noticed the word "viable" in your question.

@chriscoyier And I will fight you to the death if you say otherwise.

Tech companies are often guilty of making huge assumptions about their users' environments, sacrificing and as a result.

Interesting to see how many tech sites have slow Largest Contentful Paint (LCP) times (as slow as 34 seconds!) on slower mobile connections:
