推荐答案

除非您的页面大小以兆字节为单位，否则结果将毫无意义。

Unless your page has size in megabytes, the result will be meaningless.

这是因为连接，发送请求和等待服务器发送所需的时间回复回复是非常大，下载页面，除此之外，TCP / IP还有缓慢启动。

This is because time needed to connect, send request, and wait for server to send reply back is quite large compared to time required to download the page, and in addition to that TCP/IP has slow start.

您还必须考虑浏览器将使用的缓存，代理和并行连接数（例如，可能会优先下载脚本和样式，从而使页面下载时间成为ppear慢）。

You also have to take into account caches, proxies and number of parallel connections that browser will make (e.g. may prioritize download of scripts and styles, making page download time appear slow).
