X is rolling out a new version of its web app that it says is much faster, starting with signed-in users in one country at a time. In a blog post, principal engineer Yagiz Nizipli said a profile on X.com over a slow connection previously took more than 22 seconds before the first post appeared, versus 2.7 seconds on the new app. The post also goes into technical detail about how the updated app was built, though the available excerpt does not include those details. Because the rollout is gradual, not every signed-in user will see the new app immediately.
