Iperf – Bandwidth Measurement Tool
April 15th, 2008
Need a simple way to test the bandwidth between two hosts that you have access to? If so, then just drop Iperf onto both machines. Launch one instance as the server
iperf -s
and the other as the client
iperf -c <Server IP>
then after 10 seconds you’ll have your result.
------------------------------------------------------------ Client connecting to 192.168.1.11, TCP port 5001 TCP window size: 8.00 KByte (default) ------------------------------------------------------------ [1912] local 192.168.1.21 port 1107 connected with 192.168.1.11 port 5001 [ ID] Interval Transfer Bandwidth [1912] 0.0-10.0 sec 26.7 MBytes 22.4 Mbits/sec
Iperf is readily available as a binary for various operating systems, i.e.: Linux, FreeBSD MacOS, Windows, etc. The source code is also available.
