iperf简易使用说明--基于linux+buildroot

1.保证两台主机在同一个LAN内，彼此可以ping通对方；

host1: 192.168.3.10

host2:192.168.3.1

2.host2一方做server：

在host2上启动server:iperf -s &

[root@rk3399:/opt]# iperf -s
------------------------------------------------------------
Server listening on TCP port 5001
TCP window size: 85.3 KByte (default)
------------------------------------------------------------
[  4] local 192.168.112.16 port 5001 connected with 192.168.112.254 port 43928
[ ID] Interval       Transfer     Bandwidth
[  4]  0.0-10.0 sec  1.03 GBytes   885 Mbits/sec
[  4] local 192.168.112.16 port 5001 connected with 192.168.112.254 port 43930
[  4]  0.0-10.0 sec  1.09 GBytes   936 Mbits/sec
 

3. host1做client,连接host2进行测试：

iperf -c 192.168.3.1 -i 1 

[root@rk3399:/opt]# iperf -c 192.168.112.60 -i 1
------------------------------------------------------------
Client connecting to 192.168.112.60, TCP port 5001
TCP window size: 45.0 KByte (default)
------------------------------------------------------------
[  3] local 192.168.112.16 port 56684 connected with 192.168.112.60 port 5001
[ ID] Interval       Transfer     Bandwidth
[  3]  0.0- 1.0 sec  88.4 MBytes   741 Mbits/sec
[  3]  1.0- 2.0 sec   112 MBytes   941 Mbits/sec
[  3]  2.0- 3.0 sec   112 MBytes   943 Mbits/sec
[  3]  3.0- 4.0 sec   112 MBytes   941 Mbits/sec
[  3]  4.0- 5.0 sec   112 MBytes   944 Mbits/sec
[  3]  5.0- 6.0 sec   112 MBytes   941 Mbits/sec
[  3]  6.0- 7.0 sec   112 MBytes   944 Mbits/sec
[  3]  7.0- 8.0 sec   112 MBytes   944 Mbits/sec
[  3]  8.0- 9.0 sec   112 MBytes   938 Mbits/sec
[  3]  9.0-10.0 sec   112 MBytes   944 Mbits/sec
[  3]  0.0-10.0 sec  1.07 GBytes   922 Mbits/sec
 

4.收+发双测试：这个很实用，可以同时测到双向的速度

iperf -c 192.168.3.1 -i 1 -d
