Introduction to Web Performance Engineer (WPE)
Web Performance Engineer (WPE) is a specialized tool designed to assist web developers and performance engineers in optimizing website performance. Its core function is to analyze, diagnose, and provide actionable recommendations for improving web performance metrics, particularly those related to Core Web Vitals such as Largest Contentful Paint (LCP), First Input Delay (FID), and Cumulative Layout Shift (CLS). WPE is structured to guide users through detailed checklists, offer targeted solutions based on specific issues, and generate reports in multiple formats (PDF, DOCX, CSV) for easy reference. For example, if a developer uploads a PageSpeed Insights report indicating slow LCP, WPE will provide a customized plan to address the issue by suggesting optimizations such as lazy loading, image compression, and using modern formats like WebP.
