Cartographer + move_base runs at the same time,Control loop missed its desired rate。(cmd_val frequency is extremely low)

The computer used is: NVIDIA Jetson TX2, cpu utilization is close to 100%. Is this a normal phenomenon or a configuration problem?

/move_base/local_costmap/obstacle_layer/obstacle_range: 5.0
/move_base/local_costmap/obstacle_layer/raytrace_range: 5.5

Appropriately reduce these two parameters

You're trying to do too much with your CPU, if you're at 100% utilization, you're missing rate because you don't have enough cycles to accomplish that processes computational tasks.

You'll need to either do less, offload some computation, or try to tune things to run at tractable rates. The rule of thumb for this type of thing is to have your CPU running at about 80% so that there's enough juice for the sudden bursts of work.

Thank you very much for your answer! I have enhanced cpu performance, and now the occupancy rate is around 60%, but there are still the above problems.

[ INFO] [1563279138.784172362]: Resizing costmap to 650 X 680 at 0.050000 m/pix
[ INFO] [1563279138.795393838]: Resizing static layer to 650 X 680 at 0.050000 m/pix
[ WARN] [1563279156.227073295]: Control loop missed its desired rate of 10.0000Hz... the loop actually took18.7780 seconds
[ WARN] [1563279156.227821820]: Map update loop missed its desired rate of 1.0000Hz... the loop actually took 25.4829 seconds.

The terminal always prompts Resizing costmap, is this normal?
