300ms Faster: Reducing Wikipedia's total blocking time
I've noticed that Wikipedia is, now days, extremely fast if I'm not logged in. Just about any article loads near-instantaneously, it might even be faster than Hacker News!But if I'm logged in its much slower - there's perhaps a second or so lag on every page view. Presumably this is because there's a cache or fast-path for pre-rendered pages, which can't be used when logged in?
