Front-End Performance Optimization: Traditional and Perceptual Metrics

Front‑end performance, crucial for traffic and conversion, can be optimized by combining traditional non‑visual metrics (like DNS time, TTFB, and First Paint) with perceptual visual metrics (FCP, FMP, Speed Index, PSI), using tools such as Lighthouse, Chrome DevTools, and the custom Twilight video‑analysis utility, as demonstrated by a Vue‑based flight‑ticket site achieving up to 80% FMP improvement.
