linux服务器读写速度，在线测试服务器速度

1、登录到服务器的Home目录下，下载speedtest.py

sudo wget https://raw.githubusercontent.com/sivel/speedtest-cli/master/speedtest.py

2、加上执行权限，需要有python环境支持下执行：

sudo chmod 755 speedtest.py
./speedtest.py

[wuyun@localhost home]$ ./speedtest.py

最好选择网络空闲时段再测试。它会自动发现离你最近的Speedtest.net服务器（地理距离），然后显示测试的网络上/下行速率。
