Dear, QCT
I've tested ROS2 msg latency using irobot ros2 performance tool on RB5 development kit.
(github : https://github.com/irobot-ros/ros2-performance/)
But the late_msgs are 10 times more often than Raspberry Pi3
(raspberry pi3 result : https://github.com/irobot-ros/ros2-performance/tree/dashing/performances...)
Please refer to the below details.

hello customer,
please test with below command to check whether it can be improve.
adb shell "echo performance > /sys/devices/system/cpu/cpu*/cpufreq/scaling_governor"
Thanks
