After implementing Compression Dictionaries back in December, I sat down with @yoav.ws and @patmeenan.com to discuss getting the most out of them and provide some visuals for those new to the concept. Check out the video below: youtu.be/YR2er3EiYnM / lessonsofacto.com/videos/032-c...

My friends over at RUMvision.com have sent me a lovely gift. I think my boys love it as much as I do, though they are mostly interested in fighting over occupation of the box. Thank you @jordyscholing.bsky.social, @erwinhofman.bsky.social and @karlijnlowik.bsky.social ❤️

Funny thing; I was checking Baseline support for view-transitions for a publisher client of our and noticed that the support for Safari was quite high... FYI: Safari supports view-transitions on version 18 or above. Combining Baseline with RUM data is goated...

A side- effect of #speculationrules is that CrUX shows a degradation in TTFB. Reason? CrUX unfortunately excludes TTFB from pre-rendered pages (subsequent navigations). As a result, the CrUX dataset for TTFB contains a relatively larger amount of slower landing pages. #webperf

Some fun stats: The average Core Web Vitals of RUMvision domains (mobile P75) • LCP: 1988ms • CLS: 0.025 • INP: 198ms 😅 • FCP: 1356ms • TTFB: 767ms Q1 2025 I want that INP to be below 180ms. This is a sample of 25M datapoints.

Too bad to see that when you are working hard to get a website to use bf_cache as much as possible, but an external party (Meta JS SDK) ensures that the percentage of bf_cache navigations is now back to square one. It was not an issue before, so I think there's been a change in their code?

Nothing better than fixing TTFB so you can fully work on front-end related optimizations...

What are all the reasons "real user metrics" for Core Web Vitals would differ from Google's PageSpeed Insights? I'll start: - RUM data may include non-Chrome browsers (For LCP and INP they would all be Chromiums) - Google only counts users who have Chrome sync on and opted into data sharing

Should core web vitals thresholds be different in parts where it’s really hard to pass? 🤨 (Purely so that those companies can have the “SEO boost”) Bold question, but curious about your thoughts. #PerfNow

Significant growth in how many videos we put on our sites, but also a good amount of extra JS 😤 #PerfNow @tammyeverts.bsky.social
