It looks like there were several different issues discussed here.

The ros2 topic issue seems to be a bug in the truncation of the output and printing to console is taking a very long time. This should be addressed by https://github.com/ros2/ros2cli/pull/126

The issue difference of FPS between C++ and Python that can be addressed by running the python interpreter in optimized mode: setting the environment variable `PYTHONOPTIMIZE=0` or passing `-O` to the python invocation.
