Bandwidth Measurement

Commands
On the server:

iperf -s

On the client:

iperf -c IP -i 1 -t 60

Results

Network type	Average bandwidth
Real	855 Mbits/sec
Hub	194 Mbits/sec
Switch	185 Mbits/sec
Router	394 Mbits/sec

Bandwidth/Jitter/Loss Measurement

Commands

On the server:

iperf -u -s

On the client:
