准备工作：
安装epel源
rpm -ivh http://mirrors.sohu.com/fedora-epel/6/x86_64/epel-release-6-8.noarch.rpm
更新本地cache安装iperf
yum makecache -y yum install iperf -y
测试工作：
192.168.0.244为server端，192.168.0.236为client端
在server端和client端可以查看到传输的情况，还可以通过ifstat, iptraf查看网卡的流量
TCP测试
server(0.244)
iperf -s -i 1 -s 服务器模式 -i 报告显示间隔秒数
client(0.236)
iperf -t 20 -i 1 -c 192.168.0.244
-t 测试用时的秒数
-c 客户端模式，后面接要连接的服务器
