When running the full launch file for the dummy example on vulcan, both the viz and the sim sensor publisher are very laggy and slow. however, this doesn't happen when I run the same loop locally on a laptop. Need to debug.

An update: this only happens when using MultiThreadedExecutors. It turns out there's this open issue about it here: ros2/rclpy#1223

We can try switching to CycloneDDS to see if that resolves the issue.
