optional arguments:
  -h, --help            show this help message and exit
  --no-download         Do not perform download test
  --no-upload           Do not perform upload test
  --bytes               Display values in bytes instead of bits. Does not
                        affect the image generated by --share, nor output from
                        --json or --csv
  --share               Generate and provide a URL to the speedtest.net share
                        results image, not displayed with --csv
  --simple              Suppress verbose output, only show basic information
  --csv                 Suppress verbose output, only show basic information
                        in CSV format. Speeds listed in bit/s and not affected
                        by --bytes
  --csv-delimiter CSV_DELIMITER
                        Single character delimiter to use in CSV output.
                        Default ","
  --csv-header          Print CSV headers
  --json                Suppress verbose output, only show basic information
                        in JSON format. Speeds listed in bit/s and not
                        affected by --bytes
  --list                Display a list of speedtest.net servers sorted by

  --server SERVER       Specify a server ID to test against
  --mini MINI           URL of the Speedtest Mini server
  --source SOURCE       Source IP address to bind to
  --timeout TIMEOUT     HTTP timeout in seconds. Default 10
  --secure              Use HTTPS instead of HTTP when communicating with
                        speedtest.net operated servers
  --no-pre-allocate     Do not pre allocate upload data. Pre allocation is
                        enabled by default to improve upload performance. To
                        support systems with insufficient memory, use this
