What way would you suggest measuring this? Duration between TTFB and when user events first get pumped?
- bluesmoon 6y agoThe simplest way to measure impact on users would be to just use boomerang which gets you all of this out of the box: https://github.com/akamai/boomerang https://github.com/akamai/boomerang To do it yourself, you need a combination of PainTiming and measuring LongTasks or study the periodicity of setInterval/requestAnimationFrame The above works for synthetic as well as real users. If you're able to measure real users directly, then you'd also want to look at Input Delays, Rage Clicks, Dead Clicks, Missed Clicks, Scroll Jank.
