Using curl to output detail time consuming of http
1. prepare template file
e.g. curl.txt
\n
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
\n
2. curl with the following command
curl -w "@curl.txt" -o /dev/null -s https://www.google.com
time_namelookup: 0.004
time_connect: 0.014
time_appconnect: 0.141
time_pretransfer: 0.141
time_redirect: 0.000
time_starttransfer: 0.153
----------
time_total: 0.165
