At my company, we’ve done an excellent job showing people the value of using user-based metrics like the Core Web Vitals for performance testing. But this has also become a bit of a two-edged sword.
According to the Google Search Console, mPulse, CrUX etc, we have excellent CWV scores.
My concern is that the page weight of our homepage and other CMS content heavy pages is around 5mb, on the small end. Sometimes if they go crazy with videos and haven’t been paying attention, they can balloon up into the 15mb range.
From a user’s standpoint (and thus, from my standpoint as the performance guru), if all that weight is lazy loaded and the page appears fast, does it really matter?
