Wget 的响应时间

我正在尝试调试一些网络问题，我想追踪不同事件的响应时间。例如，连接到服务器所需的时间与服务器呈现页面所需的时间（所以time wget ...行不通）

我一直在使用 wget

$ wget --spider www.google.com
Spider mode enabled. Check if remote file exists.
--2013-11-22 13:56:10--  http://www.google.com/
Resolving www.google.com... 74.125.224.52, 74.125.224.49, 74.125.224.48, ...
Connecting to www.google.com|74.125.224.52|:80... connected.    <-- Time here
HTTP request sent, awaiting response... 200 OK                  <-- Time here
Length: unspecified [text/html]
Remote file exists and could contain further links,
but recursion is disabled -- not retrieving.

有没有办法为各种请求添加时间戳？

ab从包中尝试apache2-utils。它会告诉您连接、处理和等待时间：
