Write the following lines into a text file and save as "ctemplate.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 | |
Use the template with cUrl to display timing data: | |
'curl -w "@ctemplate.txt" -o /dev/null -s http://wordpress.com/' | |
Output should look something like this: | |
time_namelookup: 0.001 | |
time_connect: 0.037 | |
time_appconnect: 0.000 | |
time_pretransfer: 0.037 | |
time_redirect: 0.000 | |
time_starttransfer: 0.092 | |
---------- | |
time_total: 0.164 | |
Alternatively you can place a file in your home directory with curl configuration: ~/.curlrc | |
write-out = "\n download_size: %{size_download}\n\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" | |
dump-header = - | |
output /dev/null |
