Server Response Problem for Ros2

[SUNBinzhi]

Hi！We are using tm 5-900 robot arm to test some algorithm in ubuntu 22, ros 2 humble. The communication we use is the service-client.
When we repeatedly sending command(joint angles) to the robot using a client in ros 2, if the frequency is exceeded 2Hz (0.5s/command) there will be a large delay of the robot to execute the command. So this will cause the robot to work not very smoothly. Is there any method to speed up the frequency for the robot to execute commands?

I'm about to buy one of those robots.
I'm familiar with low level control of robots sending joints command at 1kHz (Kuka Iiwa / Emika Franka)
I was wondering if I could do the same with this robot ?
