CURL time

From this brilliant blog post... https://blog.josephscott.org/2011/10/14/timing-details-with-curl/

cURL supports formatted output for the details of the request (see the cURL manpage for details, under -w, –write-out ). For our purposes we’ll focus just on the timing details that are provided. Times below are in seconds.

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 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

And here is what you get back: time_namelookup: 0.001s time_connect: 0.037s time_appconnect: 0.000s time_pretransfer: 0.037s time_redirect: 0.000s time_starttransfer: 0.092s ---------- time_total: 0.164s I have not yet seen an option to output the results in microseconds, but if you're aware of one, post in the comments below.

Make a Linux/Mac shortcut (alias) alias curltime="curl -w "@$HOME/.curl-format.txt" -o /dev/null -s " Then you can simply call...

curltime wordpress.org Thanks to commenter Pete Doyle!

Make a Linux/Mac stand-alone script This script does not require a separate .txt file to contain the formatting.

Create a new file, curltime, somewhere in your executable path, and paste in:

#!/bin/bash

curl -w @- -o /dev/null -s "$@" <<'EOF' time_namelookup: %{time_namelookup}\n time_connect: %{time_connect}\n time_appconnect: %{time_appconnect}\n time_pretransfer: %{time_pretransfer}\n time_redirect: %{time_redirect}\n time_starttransfer: %{time_starttransfer}\n ----------\n time_total: %{time_total}\n EOF Then call it the same way as the alias:

curltime wordpress.org

Make a Windows shortcut (aka BAT file) Create a new text file called curltime.bat in the same folder as curl.exe and curl-format.txt, and paste in the following line:

curl -w "@%~dp0curl-format.txt" -o NUL -s %* Then from the command line you can simply call:

curltime wordpress.org (Make sure the folder is listed in your Windows PATH variable to be able to use the command from any folder.)
