Gilles added a comment to T232174: 1st Sept: Regression in start render/last visual change (desktop and mobile)?.

The device emulation is a bit of a black box. It might be good to verify that there wasn't a system update on the host around that time or something like that. I imagine that updating some linux library on the system could have a side-effect like this for example. Or a hardware incident of some kind on the host.

Gilles added a comment to T232174: 1st Sept: Regression in start render/last visual change (desktop and mobile)?.

Comparing a run today and one from September 2, I see the exact same requests before reaching the first render. The bandwidth graph up to that point is pretty much the same as well. The only different seems to be that the browser main thread just takes a lot longer to run before reaching the initial render:

The editors replied, this gets cleaned up by "bots and gnomes". These spikes happen regularly upon changes to those templates, this one was just bigger than usual. I'm closing this, as this is a very likely explanation, based on the rise and drops corresponding exactly for the Barack Obama article.

Digging further into specific loadEvendEnd and cpu score slices for those weeks, the results are quite suspicious, with users in August consistently being happier by 2%, even for the same cpu score and loadEventEnd ranges. I think we can't rely just on those 2 weeks at random, and we need to look at the trend over time, by week or by month, before drawing any conclusions.

Follow-up idea: look at specific cpuscore/loadEventEnd range in April and now and see if the satisfication ratio is the same. I.e. did users' expectations evolve during that period?

I will enable this for a short period on eswiki and ruwiki to measure the impact. But the unresolved issues around printing, especially considering how prominently we advertise printing in the sidebar, makes this new browser feature somewhat impractical for now.

If the devroom gets approved, we're supposed to run a CfP ourselves. I think we should weigh our own talk ideas against what everyone else out there will propose. Preference should go towards what's the most on topic in the context of FOSDEM. A lot of general Web Performance talks don't have any FLOSS/open standards angle.

Gilles added a comment to T229721: Try Display Locking API.

Conceivably we could break down the page into 2 parts. The critical content, which can be left as-is. And the non-critical content (eg. article content past the first paragraph) in a separate element. That element, as soon as it's created, is locked (and disappears). Then whenever we want - for instance, once the browser has download all of it and reached another chunk of inline JS - we can ask the browser to render it cooperatively. Which should be less aggressive than the default processing/painting of DOM, which is blocking.

The print feature in the sidebar seems to rely on a different version of the page, though (with different HTML), for which we could conceivably disable image lazy loading. The issue remains for users who invoke the browser's print feature directly themselves on an article.

Dimension information is exposed in attributes for thumbnails, for Media Viewer's sake. I don't think that Media Viewer relies on the load event to wait for anything, as users can click on thumbnails before the load event.
