Network performance testing in Linux

IPERF is a network speed testing tool. It is reliable if you have two servers, and you want to measure network speed between them.

It can be installed using yum
# yum install iperf

For testing, one iperf instance runs as a server on one server and another iperf instance runs as a client on the other server.

For running iperf as a server
# iperf -s
Server listening on TCP port 5001

And for running iperf as a client
# iperf -c
Client connecting to, TCP port 5001 TCP window size: 16.0 KByte (default) 

[3] local port 47326 connected with port 5001 
[ID] Interval Transfer Bandwidth 
[3] 0.0-10.0 sec 267 MBytes 228 Mbits/sec
