Sometimes, in order to test the network, you need to return the time spent in each phase, such as the time spent parsing DNS, the time it takes to establish a connection, the time it takes from establishing the connection to preparing for transmission, the time from establishing the connection to the start of the transmission, the whole process, the amount of data downloaded, the download speed, the amount of data uploaded, the upload speed, and so on. The following script gets the above information:
The code is as follows:

Use strict
Use Data::Dumper
Use WWW::Curl::Easy

Print "Usaging: $0 url\ n"
Print "For example: $0 www.ttlsa.com\ n"
Exit
}
My $curl = new WWW::Curl::Easy

$curl- > setopt (CURLOPT_HEADER,1)
