Dear, QCT

I've tested ROS2 msg latency using irobot ros2 performance tool on RB5 development kit.

(github :

But the late_msgs are 10 times more often than Raspberry Pi3

(raspberry pi3 result :

Please refer to the below details.

--- Test Enviroment ---

1. Image Version : QRB5165.UBUN.1.0-211118
2. ROS2 Version : Dashing
3. ROS2 Performance tool cmd parameter: 
$./benchmark topology/sierra_nevada.json -t 600 --ipc on -s 1000 --late-percentage 20 --late-absolute 5000 --too-late-percentage 100 --too-late-absolute 50000


---- Test Reulst----

received[#]    mean[us]  late[#]   late[%]   too_late[#]    too_late[%]    lost[#]   lost[%]
