time_connect – Display the time in seconds from the connect was noticed by curl until the first byte arrived.
time_namelookup – Display the time in seconds it took from the start until the name resolving was completed.
time_pretransfer – Display the time in seconds it took from the start until the file transfer was just about to begin.
time_starttransfer – Display the time in seconds from the connect was noticed by curl until the first byte arrived.
time_total – The total time in seconds to perform the operation.
-s – Don’t display the progress bar.
-w – Used to define what to display on output.
-o – Used to write complete output to \/dev\/null.
If your website is HTTPS, you can run the following command:<\/p>\n\n\n
\ncurl -s -w 'Testing Website Response Time for :%{url_effective}\\n\\nLookup Time:\\t\\t%{time_namelookup}\\nConnect Time:\\t\\t%{time_connect}\\nAppCon Time:\\t\\t%{time_appconnect}\\nRedirect Time:\\t\\t%{time_redirect}\\nPre-transfer Time:\\t%{time_pretransfer}\\nStart-transfer Time:\\t%{time_starttransfer}\\n\\nTotal Time:\\t\\t%{time_total}\\n' -o \/dev\/null https:\/\/www.linux.com\n<\/pre><\/div>\n\n\n
You should get the following output:<\/p>\n\n\n

If you don’t want to run a long command every time, you can create a file named curl_test.txt and all required options:<\/p>\n\n\n\n
nano curl_test.txt
Add the following lines:<\/p>\n\n\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
Save and close the file then run the following command:<\/p>\n\n\n\n
curl -w “@curl_test.txt” -o \/dev\/null -s https:\/\/www.howtoforge.com
You should get the following output:<\/p>\n\n\n\n
time_namelookup: 0.013
time_connect: 0.056
time_appconnect: 0.160
time_pretransfer: 0.160
