1 | Baseline Performance Measurement

NVIDIA AGX Orin Kit

CPU and Memory Usage:

htop

Disk I/O:

sudo iotop

Network I/O:

iftop -i <network_interface> { eth0 | wln }

Toggle DNS Resolution (n): Resolving hostnames can help you identify devices more easily.

Toggle Source and Destination Ports (S, D): This helps you see which ports are being used for communication, which can be useful for understanding the types of traffic.

Sort by Bandwidth Usage (1, 2, 3): Sort by the columns to focus on the most significant traffic. For instance, pressing 1 will sort by the first column, typically showing the highest bandwidth users.

Toggle Cumulative Line Totals (T): This gives you a running total of the data transferred, which can be useful for longer-term monitoring.

Set Screen Filter (l): If you're only interested in traffic involving a specific host or network, you can set a filter to display only relevant data.

Use Bar Graph Display (b and B): The bar graph can give a visual representation of traffic, making it easier to spot peaks and trends.

Exit iftop: Press q to quit when you're done.

3 | Performance Measurement During Operation

NVIDIA AGX Orin Kit

Use iperf for Network Bandwidth:

iperf3 -s

Run iperf Client on PC:

iperf3 -c <orin_ip> -t 60 -i 10

PC

Measure USB Transfer Rates for Sensors:

dd if=/dev/zero of=/dev/null bs=1M count=1024

Use iperf for Network Bandwidth:

iperf3 -s

Run iperf Client on Orin Kit:

iperf3 -c <pc_ip> -t 60 -i 10
