X Rolls Out Faster Web App, Country by Country

X has released a new version of its web app that it says is much faster than before. The update is rolling out gradually to signed-in users, one country at a time, so it may not show up on your account right away.

The X web app: from 22 seconds to 2.7 seconds

X principal engineer Yagiz Nizipli explained the changes in a blog post. He asks readers to imagine opening a profile on X.com over a slow connection. On the old web app, you would stare at the X logo for more than 22 seconds before the first post appeared. On the new version, the first post shows up in 2.7 seconds.

The blog post also covers the technical side. According to X, the new app replaces the three servers it used to run for people, search crawlers, and link previews with just one.

The slow-connection scenario X uses as its example will feel familiar to anyone whose signal tends to come and go. Still, these numbers are claims from X's own team, and since the rollout is staged by country, you may have to wait a bit before you notice the difference.
