Best Practice stereo cameras on Jetson AGX XAVIER

Hello Forum,
I have just set up JetPack on my XAVIER Developer kit and installed Basler Pylon viewer.
I hooked up my two Basler 1920-155um through USB3.0 and started continuous shots on them both, simultaneously.
I notice that the CPU usage quickly increases to 100%. In the attaches screenshot you see Pylon Viewer consumes 82% CPU and my two cameras are set to 60 fps.

Are there any users with stereo camera experience out there?

What is the best practice?

My goal is to write some python software that uses Neural Network and AI to do object detection, in short.

To leverage hardware acceleration, on Xavier, please check documents of gstreamer and tegra_multimedia_api.

And DeepStream SDK for AI usecases:
