Compile and install : 

1. download source from Home Page

http://downloads.sourceforge.net/project/iperf/iperf-2.0.5.tar.gz

2../configure ; make ; make install

What it can do ?

Test TCP :  Bandwidth

Test UDP:  Bandwidth, delay, datagram loss.

TCP Sample : 

Server  :

# iperf -s 127.0.0.1

iperf: ignoring extra argument -- 127.0.0.1

------------------------------------------------------------

Server listening on TCP port 5001

TCP window size: 85.3 KByte (default)

------------------------------------------------------------

...

Client :

# iperf -c 127.0.0.1 -i 1

------------------------------------------------------------

Client connecting to 127.0.0.1, TCP port 5001

TCP window size:  169 KByte (default)
