最近一个用户在老兵云平台买了一台4核4G 10M带宽配置的武汉固定IP云主机，装了Ubuntu 18.04 64位系统，ping自己的网站发现延迟比较大，质疑我们给的带宽不够。为了证明我们的带宽没问题，给他装了WonderShaper测速用数据说明
WonderShaper是用来对特定网卡进行快速限速的工具，它实际是对linux的tc命令进行封装后的shell脚本，所以使用成本比tc更低，更容易上手，以下配合测速工具speedtest一起使用
#直接拉取WonderShaper，开箱即用 git clone https://github.com/magnific0/wondershaper.git root@****-5491:/home/soft/wondershaper# ./wondershaper -v Version 1.4.1 root@****-5491:/home/soft/wondershaper# #网速测试工具speedtest安装(Ubuntu) apt install speedtest-cli --yum install speedtest-cli (centos)

1KB/s = 8kbps = 8kb/s 比如一般100M的宽带，实际是100Mbps=(100/8) MB/s=12.5 MB/s
使用WonderShaper对网卡进行限速，在测试时可以针对性的指定网卡，指定上传速度或者指定下载速度，在测试中上传和下载速度是互不影响的，可以只限制一方。
