Wget com tempo de resposta

Question

Estou tentando depurar alguns problemas de rede e gostaria de rastrear o tempo de resposta para diferentes eventos. Por exemplo, o tempo que leva para se conectar ao servidor versus o tempo que levou para o servidor renderizar a página (portanto, time wget ... não funcionará)

Eu tenho usado o 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.

Existe uma maneira de adicionar carimbos de hora às várias solicitações?

Teste ab do pacote apache2-utils . ele informará a conexão, o processamento e os tempos de espera:
