When web performance degrades, the impact is immediate.

Conversions drop. UX suffers. SEO follows.

The problem? These issues are often detected too late.

With @chromedevtools.bsky.social, we can streamline Web Performance Debugging with the help of the AI assistant

#WebPerf #PerfTools #PerfDebugging
A screenshot of a performance review interface titled “Perf Reviews” with the question “Which LCP phase was most problematic?” An AI assistant response shows analysis results indicating that the “Time to first byte (TTFB)” phase contributed 4,311 ms (92.8%) of the total 4,648 ms Largest Contentful Paint time, while “Element render delay” contributed 337 ms (7.2%). Below the response are action buttons such as “How can I reduce the time to first byte (TTFB)?” and “What caused the LCP element to render slowly?”
