Iperf

Test TCP network performance

iperf3 communicates over port 5001 by default when testing TCP performance; however, this port is configurable using the -p switch. Ensure that security groups are configured to allow communication over the port that will be used by iperf3.

Configure one instance as a server to listen on the default port or specify an alternate listener port with the -p switch:

$ sudo iperf3 -s -p 80

Configure a second instance as a client and run a test against the server with the desired parameters. For example, the following command initiates a TCP test against the specified server instance with 10 parallel connections on port 80:

sudo iperf3 -c 10.0.2.176 -i 1 -t 60 -V -p 80

Using the iperf3 parameters described, the output displays the interval (60 seconds) per TCP connection, the data transferred per connection, and the bandwidth utilized by each connection.

The iperf3 output shows that the total bandwidth transmitted across all connections was 9.60 Gbits/sec:
