Imarlier added a comment to T158084: Mediawiki namespace pages, including CentralNotice banners, are slow to save.

Analysis at https://phabricator.wikimedia.org/T203925#4616856 suggests that the issue is that every single content revision is being pulled individually from the cache. Even when memcache returns quickly (500us), in some instances we're making tens of thousands of independent calls to memcache and they're adding up. It looks like maybe some sort of batching in MessageCache::getFromDB is called for, but I haven't really deep-dived.

I haven't thought through the ideal way to do this, but what about adding an additional test for a very simple page -- like a page that just loads a single image or something, maybe even from a file:/// URL.

Simply noting that if we were to do this, it would be ideal for device detection to be based on CSS selectors. Google and others use CSS selectors, provided as the media attribute of a <link rel="alternate"> tag, to decide whether to direct users to the desktop or mobile version of a site when they're served from different URLs.
