这是一款类似ping命令的小工具，用来测试链路暂态带宽近似工具。
usage:
-h: help, display speedy help information.
As client:
-cip:port
ip:(default=127.0.0.1)
port:(default=55555)
-n:thread number(default=1)
-l:blk size(default=1024)
-m:short linked module(1:进入短链接模式,默认是0,长连接模式.)
-r:random seconds(单链接模式下,随机发起连接的最大时间间隔n.)
-t:fix seconds(单链接模式下,n秒发送一条探测消息.)
-r 与 -t互斥.
such as:
speedy -c[ip:port] [-n2 -l1024]
speedy -c[ip:port] [-m1 -l10240 -r5]
As server: -sport:(default=55555) -t:sample time(长连接模式下使用default=1 second) -m:short linked module(1:进入短链接模式,默认是0,长连接模式.)
such as:
speedy -s[port][ -t1]
speedy -s[port][ -t1][-m1]
