As shown in T206228, we usually spend more time generating page edit metadata than loading the actual page HTML. Page metadata includes
- Edit notices
- Edit checkboxes (minor edit etc.)
- Used templates
- Red-link information
- Latest revision and timestamp info
Firstly we should investigate whether this is a regression, or something we've just not noticed before.
Secondly, none of this data should block the loading of the editor, so we should be able to make the time to interactive lower in VE.
