Thanks. I added tcp_nodelay=True, but see no improvement on my computer...

2023-04-24 10:00:26 -0500 marked best answer diagram tool for the design of ros2 packages

Hi, I need to develop some ROS2 packages for my robot. Before writing each package, I want to draw a diagram for the package relations (e.g. the message, the class calling between them), like a class diagram?

Is there a name for this diagram and is there any tool for this?

The final diagram may look like rqt_graph. But it is designed before every package is prepared.

There seems to be a "package diagram" in starUML. But I'm not sure whether this "package diagram" satisfies .

Thanks for any help!
