performance.now()

the web performance conference11-12 November 2021, Amsterdam

On 11th and 12th of November, 2021 performance.now() will return to Amsterdam! The 2019 edition was a massive success, but we had to skip 2020. Now that the Covid crisis may be receding we hope an in-person conference is once more possible.

Yes, an in-person conference. At an actual venue. With actual people.

We'll stream and record all sessions so you can also enjoy performance.now() from the comfort of your home or office if you so choose. Still, if we have to cancel the in-person conference we'll cancel the online one as well.

Selected by our program co-chairs Tim Kadlec, Tammy Everts, and Harry Roberts, our speakers will treat topics and case studies including JavaScript, CSS, performance culture, PWAs, image optimization, Web Vitals, performance budgets, frameworks, ecommerce, performance culture, monitoring, mobile browsers, and perceived performance.

Sounds good, right? We bit the bullet and started ticket sales—sort of. We're also looking for sponsors.

Pre-registration for tickets is now open. This year ticket sales will be more complicated than usual due to the possibility of a late and sudden cancellation.

We have no idea if this is going to work, but we're going to try. What about you?
