url-timings records the average request times for a set of urls, broken down to dns lookup time, tcp connection time, ssl handshake time, processing time and transfer time. Upload and download sizes for all requests are also recorded.
Python and pip.
git clone [email protected]:kajic/url-timings.git
cd url-timings
pip install -r requirements.txt python timings.py -u example-urls.txtGiven example-urls.txt with the following urls:
https://google.com
https://twitter.com
https://tumblr.com
https://facebook.com
https://wordpress.com
Running python timings.py --urls example-urls.txt -c 20 --parallel will produce the average times based on 20 requests for each url:
$ python timings.py -u example-urls.txt

+-----------------------+---------+---------+-------+-----------+-----------+--------+---------+---------+timings.py uses curl to make requests and generate timings. The following description of table columns is an adaptation of curl's --write-out option.
sizeu- The total amount of bytes that were uploaded.sized- The total amount of bytes that were downloaded.dns- The time, in seconds, it took for name resolving to complete.tcp_con- The time, in seconds, it took for the TCP connection to the remote host (or proxy) to be established.ssl_con- The time, in seconds, it took for the SSL/SSH/etc connect/handshake to the remote host to be completed.calc- The time, in seconds, it took for the server to process the request.trans- The time, in seconds, it took for the response to be transfered.total- The total time for the request, in seconds.
Usage:
timings.py [--urls=URLS] [--fetch-count=COUNT] [--parallel]
timings.py --version
Options:
-h --help show this help message and exit
-v --version show version and exit
-u --urls=URLS path to urls file
-c --fetch-count=COUNT number of times to fetch each url, for averaging purposes [default: 1]
-p --parallel when -c > 1, do requests in parallel [default: False]
