Testing Bacula Machines Network Capacity – iperf

This is a nice way to detect network bottlenecks at Bacula machines transferences. You must have the iperf (Linux and Windows) application in both sides (e.g.: client & storage).

yum install iperf

or

apt-get install iperf

The test:

1. In one of the machines, normally the one that receives connections (storage daemon), start iperf in server mode:

iperf -s

2. In the other machine, start the connection test to the prior machine (example IP address):

iperf -c 192.168.0.10

3. The output should be printed in a few secconds:

------------------------------------------------------------
Client connecting to localhost, TCP port 5001
TCP window size: 2.50 MByte (default)
------------------------------------------------------------
[ 3] local 127.0.0.1 port 56882 connected with 192.168.0.10 port 5001
[ ID] Interval Transfer Bandwidth
[ 3] 0.0-10.0 sec 38.0 GBytes 32.7 Gbits/sec
