Feel free to close this quickly if I miss read the code... afaict after preloadModuleInfo we validate the cache for every logged in user? Does this mean we running filestat for every resource file every 5 min for every logged in user? If not already doing this, the RL could use global filestat times cache so its not validated for every logged in user so often? * Top level svn file reading. You could save a lot of filestat calls by just parsing revision from directory level svn files ( if available ). * The majority of mediaWiki installs they simply won't be modifying any of the release files, a global like $wgResourceLoaderCheckForFileChanges = false by default might not be a bad idea. What does ResourceLoaderFileModule::getModifiedTime-filemtime profile time look like for sites without squid in-front of mediaWiki? Maybe this is a non issue because of operating system level filestat cache? But might be painful for sites on network file systems.

No. Squid caches for *content* are bypassed for logged-in users. The Varnish caches for load.php are shared across all users, logged-in or not (except for the per-user things of course), so the startup module is regenerated once every 5 minutes, not per user per 5 minutes.
