## 2. 网络性能测试
===================================================================================
-----------------------------------------------------------------------------------
# 2.1 netperf测试
-----------------------------------------------------------------------------------
cd /usr/contrib/bin/tools
--服务器端
# netserver -4 -L 192.168.30.76 -p 8000
--客户端
# netperf -H 192.168.30.76 -p 8000 -n 20 -l 60
--测试UDP发包
# netperf -t UDP_RR -H 192.168.30.76 -p 8000 -l 10 -- -r 1500 1500
# netperf -t UDP_RR -H 192.168.30.76 -p 8000 -l 10 -- -r 9000 9000

--从该节点通过访问对方的心跳IP来建立tcp连接,随后看上面抓到的TCP包即可看到mss值。如果为8960,则说明mtu为9000.
--通过netperf或ping进行发包测试,ICMP 长度为 8976
