X announced that it is deploying a new version of its web application that it describes as substantially faster than the previous iteration. The company is rolling out the updated experience to signed‑in users on a country‑by‑country basis, while the rewritten version is already live for visitors who are not logged in.
Performance gains highlighted by engineering
In a blog post, principal engineer Yagiz Nizipli illustrated the speed difference with a concrete example. He wrote that opening a profile on X.com over a slow connection on the old web app resulted in users staring at the X logo for more than 22 seconds before the first post appeared. By contrast, the same action on the new app displays the first post in 2.7 seconds. The post also detailed a backend consolidation: the three servers previously dedicated to serving people, search crawlers, and link previews have been replaced with a single server handling all three functions.
Incremental rollout for signed‑in users
The company’s rollout plan targets signed‑in users one country at a time. This phased approach allows X to monitor performance and stability in each region before expanding to the next. While the signed‑in audience experiences the transition gradually, the rewritten code is already powering the logged‑out experience and the pages that search engines crawl, according to Nizipli’s statements.
External validation from security researcher
Security researcher Jane Manchun Wong, who gained access to the updated app, posted her impressions on the platform. She described the new experience as “snappy, loads fast and many parts are polished.” Her comment adds an independent perspective on the perceived speed and polish of the new interface.
The combined statements from X’s engineering team and an external researcher suggest that the rewrite delivers a markedly quicker user experience, especially for users on slower connections. By consolidating server responsibilities and optimizing the client‑side load sequence, X appears to have reduced the time required to render a profile page by more than an order of magnitude.
As the rollout proceeds, users in each newly enabled country will see the faster version when they sign in, while those who remain logged out already benefit from the performance improvements. The company has not disclosed a specific timeline for completing the global rollout, but the incremental method implies a focus on ensuring stability before full deployment.
Overall, X’s updated web app aims to address long‑standing performance complaints by delivering content more quickly, reducing the visual idle time that users previously endured, and streamlining the server architecture that supports the platform’s core functions.
