what depends on control frequency and plannerfrequency in movebase?

I am using mobile robot. it has 3 hz control frequency while dwalocalplanner. It gets hard narrow road.

I know simtime, samplex, sample_th and other paramaters are effect the frequency. when I reduced these parameters, path planning of robot is getting worse

What can i do for increasing controlfrequency and plannerfrequency?

You should mention aspects of the robot spec; What platform, computer, LiDAR, etc. Also, do you see warning/error messages?

The robot has Lidar and Jetson Actually my problem is slow control. I want to changes to be contol_frequency 10hz, the algorithm give me loop is missing

How's the CPU loading?... Run "top -d 1" in a terminal while the problem is occurring.

It changes how often the planning/control runs, not the actual output of the planner.
