`colcon build` delay at start in Jetson Orin

[edgarcamilocamacho]

Hello!

When I run the command colcon build in my x86_64 laptop, I almost inmediatly get the message (and starts building):

Starting >>> name_of_the package
...

But when I run it in my Jetson Orin AGX, it takes from 4 to 6 seconds to show that message and start building.

Laptop environment

Docker container based on the image osrf/ros:$humble-desktop.
