Request and response times at once using curl

Source from Stack Overflow

How

1. Create a new file, curl-format.txt, and paste in:

       time_namelookup:  %{time_namelookup}s\n
           time_connect:  %{time_connect}s\n
       time_appconnect:  %{time_appconnect}s\n
       time_pretransfer:  %{time_pretransfer}s\n
       time_redirect:  %{time_redirect}s\n
   time_starttransfer:  %{time_starttransfer}s\n
                       ----------\n
           time_total:  %{time_total}s\n

2. Make a request:

   curl -w "@curl-format.txt" -o /dev/null -s "http://wordpress.com/"

   Or on Windows, it's...

   curl -w "@curl-format.txt" -o NUL -s "http://wordpress.com/"

What this does

-w "@curl-format.txt" tells cURL to use our format file

-o /dev/null redirects the output of the request to /dev/null

-s tells cURL not to show a progress meter

"http://wordpress.com/" is the URL we are requesting. Use quotes particularly if your URL has "&" query string parameters
