Core Web Vitals, Responsive RUM + Picture Perfect

May 21, 2021 @ 1:30 pm - 3:30 pm EDT


โœจ “Never on schedule, but always on time.” – Nas โœจ

It’s been quite some time, since we’ve run the meetup (Fall 2020). In part for obvious reason, but we’re delighted to essentially jump start the meetup again. We’ll get into the details of the return of the meetup @ the actual meetup, but allow us to cut right to the chase:

โœจ Friday May 21 2021 โœจ, we’re presenting what we believe is an incredible meetup, and none more important considering the moment. Our guests and the talk titles:

๐Ÿ“ Measuring Core Web Vitals
by Barry Pollard, @tunetheweb

How are Core Web Vitals measured? How do you know your fixes have had the desired effect and why are Page Speed Insights and Google Search Console still saying your sites are failing?

๐Ÿ“ Responsive RUM
by Tim Vereecke, @TimVereecke

Categorizing device types by desktop, mobile and tablet no longer works in 2021.
It is oversimplified, meaningless and likely breaks your current performance analysis on a modern responsive website.

As #perfmattersโ€‹ we need meaningful monitoring that takes into account the modern web:
– Screen dimensions
– Device pixel ratios
– Image and CSS breakpoints

Keeping it both simple and meaningful is however not easy!

Learn about the different approaches and how to apply this to your existing RUM monitoring solutions: be it free (Google Analytics), open source (Boomerang) or commercial.

๐Ÿ“ Picture Perfect
by Addy Osmani, @addyosmani

Learn the tips and tricks that help production sites deliver images that have optimal Largest Contentful Paint and minimum Cumulative Layout Shift.

๐Ÿ“Œ we’d also love to acknowledge our sponsors Wed Directions and CatchPoint for this meetup. Plan to have some surprises.

๐Ÿ“Œ We could not be more excited to have this lineup to restart the meetup (and may have one more speaker to add). Talk/presentation details will be provided in the next day or so.

Seeing that we have an international list of speakers, in different time zones, please make note of the meetup time:

๐Ÿ•ฅ 10:30AM PDT
๐Ÿ•œ 1:30PM EDT
๐Ÿ•ข 6:30PM BST ๐Ÿ‡ฎ๐Ÿ‡ช/๐Ÿ‡ฌ๐Ÿ‡ง
๐Ÿ•ฃ 7:30PM CEST ๐Ÿ‡ง๐Ÿ‡ช

We’ll have the *doors open* or start the stream 30 mins before to let ppl gather, hang in the chat.

We’d also like to announce that we’re involved in the LAZY LOAD web performance conference taking place in June:


Some of the top minds, like Patrick Meenan, Annie Sullivan, Aaron Turner and many more. By all means, scan the speakers and their talks in the above link. We’ll share more details at the meetup. But we’d also share a discount code right now:

๐ŸŽŸ use the code ‘TWP’ for 25% off before May 21

As usual: tell a friend, slack anotherโ„ข

Ok. Hope you can join us for what is likely to be one the biggest performance meetups in a hot min. We’re excited. Hope you are as well.

Chat soon, and look for an update very shorty.
