Maybe they serve more cached content to not logged users while being more careful about serving up-to-date one to the logged ones? It's just a wild guess I have

Maybe they serve more cached content to not logged users while being more careful about serving up-to-date one to the logged ones? It's just a wild guess I have no idea how it works.
- dublinben 11y agoReddit definitely makes use of it's CDN and caching for logged out users. Since they make up the significant proportion (exact statistics escape me) of visitors, it's not surprising that's where their effort has been directed. In contrast, every page load by a logged-in user requires unique database queries for things like vote status on submissions and comments.
