X says its updated web app is way faster

X has released an updated web app that is faster than its previous version, with the company rolling out the new app one country at a time for signed-in users. The new app reduces the time it takes to load a profile on X.com from over 22 seconds to 2.7 seconds. The updated app replaces the three servers used for people, search crawlers, and link previews with one server, making it more efficient. The new app is already available for logged-out users and search engine crawlers, and users have reported it feels 'snappy' and 'polished'.
