本文整理了前端與網頁開發者必須掌握的關鍵延遲數據。從瀏覽器渲染的 16.6 毫秒黃金法則、人類感知的 100 毫秒即時界線，到 Edge 網路、Serverless 冷啟動以及資料庫跨區查詢的延遲影響。透過理解這些數字，開發者能更精準地定位效能瓶頸，優化 TTFB、INP 等 Core Web Vitals 指標，打造極速的網頁體驗。
Drawing inspiration from the classic computer science reference "Latency Numbers Every Programmer Should Know," Vercel has compiled a dedicated latency guide for modern web and frontend developers, giving them concrete numerical benchmarks to reference when optimizing user experience and Core Web Vitals.
