使用 iperf 检测主机间网络带宽 参考资料： https://blogs.oracle.com/mandalika/entry/measuring_network_bandwidth_using_iperf 背景介绍： 在调试网络时，经常需要检测两台主机间的最大带宽，我一直使用iperf命令，效果很好很准确，但发现有一些运维朋友并不知道有这个工具，于是打算写篇文章简单介绍一下。 具体操作： 操作系统：CentOS6.5 x86_64 Minimal 服务器： 192.168.10.11 192.168.10.12 [root@192.168.10.11 ~]# yum install http://dl.fedoraproject.org/pub/epel/6/i386/epel-release-6-8.noarch.rpm [root@192.168.10.11 ~]# yum install iperf [root@192.168.10.12 ~]# yum install http://dl.fedoraproject.org/pub/epel/6/i386/epel-release-6-8.noarch.rpm [root@192.168.10.12 ~]# yum install iperf [root@192.168.10.12 ~]# iperf -s ------------------------------------------------------------ Server listening on TCP port 5001 TCP window size: 85.3 KByte (default) http://linux.it.net.cn [root@192.168.10.11 ~]# iperf -c 192.168.10.12 ------------------------------------------------------------ Client connecting to 192.168.10.12, TCP port 5001 TCP window size: 64.0 KByte (default) ------------------------------------------------------------ [ 3] local 192.168.10.11 port 23351 connected with 192.168.10.12 port 5001 [ ID] Interval Transfer Bandwidth [ 3] 0.0-10.0 sec 744 MBytes 624 Mbits/sec [root@192.168.10.12 ~]# iperf -s ------------------------------------------------------------ Server listening on TCP port 5001 TCP window size: 85.3 KByte (default) ------------------------------------------------------------ [ 4] local 192.168.10.12 port 5001 connected with 192.168.10.11 port 23351 [ ID] Interval Transfer Bandwidth [ 4] 0.0-10.0 sec 744 MBytes 623 Mbits/sec (责任编辑：IT) |
