I've been experimenting with the Pending Beacon API a bit (a more ergonomic and hopefully reliable way of sending beacons) and have a blog post to share the results

We're also exploring adding ResourceTiming data to the archive soon, with a focus on third-party resources common across many sites. If this is data you'd be interested in, let us know how you'd use it!

Big thanks to @nicj for the formal introduction to the @rumarchive today. An incredible project that will add immense value for the developer community, esp those tuned into web performance data. These are the kind of details that pair so well w/ what we do at WebPageTest by Catchpoint. This is for tech team leads as well as marketing even. Today's show will be edited v promptly and posted.

Hey #webperf folks! I finally had a chance to query the @rumarchive

It was fun and easy. I wanted to share the colab I wrote in case anyone's looking for examples.

I've been looking into rage clicks, which can indicate user frustration. But I wondered if the definition (three or more clicks) might be mouse-centric. So I wanted to compare the frequency of rage clicks across platforms:

colab.research.google.com/driv

Answer: mPulse sees a similar rate on Android and Desktop.
