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.

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.

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...
