# 性能分析 使用 Performance API 处理数据可视化,本地使用本地展示,不会远程收集用户任何数据,展示数据也不会对当前网页造成任何破坏。 - 关键性能指标。忽略页面卸载时间、重定向时间。 1. 首包:`responseStart - domainLookupStart` 2. 首次渲染/白屏:`responseEnd - fetchStart` 3. 首次可交互:`domInteractive - fetchStart` 4. DOM Ready:`domContentLoadedEventEnd - fetchStart` 5. 页面加载:`loadEventStart - fetchStart` - 各阶段指标瀑布流 1. unLoad:`unloadEventEnd - unloadEventStart` 2. Redirect:`redirectEnd - redirectStart` 3. AppCache:`domainLookupStart - fetchStart` 4. DNS:`domainLookupEnd - domainLookupStart` 5. TCP:`connectEnd - connectStart` 6. TTFB:`responseStart - requestStart` 7. 数据传输:`responseEnd - responseStart` 8. DOM:`domContentLoadedEventStart - responseEnd` 9. DCL:`domContentLoadedEventEnd - domContentLoadedEventStart` 10. 资源加载:`loadEventStart - domContentLoadedEventEnd` 11. onLoad:`loadEventEnd - loadEventStart` - 资源分析 1. 首页资源请求数量、加载大小和域名分布情况。 2. 请求资源域名分布,与各个域名平均耗时。 3. 未设置响应头域名分布情况。 4. http 压缩情况,未压缩分布,缓存命中率。 5. 资源类型情况。 6. 显示资源加载和 ajax 请求耗时。
