下载和上传
网络数据传输分为发送数据和接收数据两部分。上传就是向外部发送数据，下载为从外部接收数据。它们都受网络带宽和设备性能制约。 在日常网络传输中大致1Mbps=125KB/s（1:8换算）。1M宽带即指1Mbps=1000Kbps=1000/8KBps=125KBps； 因此1M的带宽下载的速度一般不会超过125KB每秒。例如上行的网络带宽为100Mbps,那么最大上传速度就是12500KB/s，也就是12.5MB/s。
用户申请的宽带业务速率指技术上所能达到的最大理论速率值，用户上网时还受到用户电脑软硬件的配置、所浏览网站的位置、对端网站带宽等情况的影响，故用户上网时的速率通常低于理论速率值。 理论上：2M（即2Mb/s）宽带理论速率是：256KB/s（即256*8=2048Kb/s），实际速率大约为103–200kB/s；4M（即4Mb/s）的宽带理论速率是：512KB/s，实际速率大约为200—440kB/s。
安装
pip install speedtest-cli
或者下载这个文件 https://raw.github.com/sivel/speedtest-cli/master/speedtest.py
修改文件名为 speed-cli即可。1

usage: speed-cli.py [-h] [--no-download] [--no-upload] [--single] [--bytes]
[--share] [--simple] [--csv]
[--csv-delimiter CSV_DELIMITER] [--csv-header] [--json]
[--list] [--server SERVER] [--exclude EXCLUDE]

--------------------------------------------------------------------------
https://github.com/sivel/speedtest-cli
optional arguments:
-h, --help show this help message and exit
--no-download Do not perform download test
--no-upload Do not perform upload test
--single Only use a single connection instead of multiple. This
simulates a typical file transfer.
--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
distance
--server SERVER Specify a server ID to test against. Can be supplied
multiple times
--exclude EXCLUDE Exclude a server from selection. Can be supplied
multiple times
--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
option to avoid a MemoryError
--version Show the version number and exit

装逼测速
看别人分享的网速比自己快那么多，想盘他们怎么办？用speedtest-fake1
