On November 21st and 22nd of November 2019 the second edition of performance.now() will take place in Amsterdam—a single track conference with fourteen world-class speakers, covering today’s most important web performance insights.

Our 2018 inaugural conference sold out at 375 attendees. This year we'll have an equally awesome line-up, so we're likely to sell out again.

Selected by our program co-chairs Tim Kadlec and Tammy Everts, our speakers will treat topics and case studies including JavaScript, CSS, performance culture, responsive design, image optimization, UX, performance budgets, frameworks, monitoring, browsers, mobile devices, and perceived performance.

All sessions are geared toward delivering takeaway action items for teams creating fast web experiences across all devices, and there'll be plenty of room to mingle with other attendees and sponsors.

“#PerfNow was an absolute blast! Huge thanks to everyone who made me feel super welcome, especially @Souders, @tkadlec, @yoavweiss and @ppk. Who knew that the #webperf community was so full of such lovely people?! Definitely returning next year!”
