CC-A80 iperf测速

suddenkiller

CC-A80跟同网段的一个设备跑iperf（busybox集成）, 连在同一个路由器下面的两个lan口
系统是我自己修改编译的lichee，kernel起来后直接进到busybox下，没有图形界面
1. CC-A80作为server, 跑TCP流一分钟的平均速率达到893Mbps
$ iperf -c 192.168.1.10  -p 5500 -t 60
------------------------------------------------------------
Client connecting to 192.168.1.10, TCP port 5500
TCP window size: 43.8 KByte (default)
------------------------------------------------------------
[  3] local 192.168.1.20 port 35449 connected with 192.168.1.10 port 5500
[ ID] Interval       Transfer     Bandwidth
[  3]  0.0-60.0 sec  6.24 GBytes   893 Mbits/sec

2. CC-A80作为client，跑TCP流一分钟的平均速率能达到649Mbps， 这里应该是我另个测试机器的性能问题
# iperf -c 192.168.1.20 -p 5500 -t 60
------------------------------------------------------------
Client connecting to 192.168.1.20, TCP port 5500
TCP window size: 20.7 KByte (default)
------------------------------------------------------------
[  3] local 192.168.1.10 port 44192 connected with 192.168.1.20 port 5500
[ ID] Interval       Transfer     Bandwidth
[  3]  0.0-60.0 sec  4.53 GBytes   649 Mbits/sec

这个速度还是比较满意的。
