Salesforce has made Lightning Experience Insights generally available in Spring '26 as part of Scale Center. The feature helps developers diagnose and optimize Lightning page performance within their own orgs. Key components include a Performance Overview using Experience Page Time (EPT) at the 75th percentile, Key Insights flagging deviations from best practices (e.g., too many components, missing Lightning CDN), Performance Trends broken down by geography and browser, and a High-Impact Slow Pages view that surfaces specific custom components causing delays. The platform has also improved overall Lightning Experience performance by 37% since the initiative began.
