一个网络速度测试工具，支持IPv4与IPv6，支持TCP、UDP、SCTP传输协议，可在Windows、Mac OS X、Linux、FreeBSD等各种平台使用，是一个简单又实用的小工具。  
常用方式举例：

S端：

iperf -s -u -i 1

      -y, --reportstyle C      report as a Comma-Separated Values
      -h, --help               print this message and quit
      -v, --version            print version information and quit
    
    [kmgKMG] Indicates options that support a k,m,g,K,M or G suffix
    Lowercase format characters are 10^3 based and uppercase are 2^n based
    (e.g. 1k = 1000, 1K = 1024, 1m = 1,000,000 and 1M = 1,048,576)
    
    The TCP window size option can be set by the environment variable
    TCP_WINDOW_SIZE. Most other options can be set by an environment variable
    IPERF_<long option name>, such as IPERF_BANDWIDTH.
