High CPU use when running multiple instances of ArgusMonoNode

[SyedShayaan]

ISSUE:
I am running a 7 gmsl camera's using the argus mono camera node and I am getting high CPU usage .

SYSTEM:

• Jetson AGX Orin Industrial
• CPU(s): 8 core
• RAM 30 gig

CAMERA:
LI-IMX568-GMSL2-105H

Furthermore, if I add isaac ros h264 encoder to the pipeline, my cpu utilization goes to 100% for all 8 cores, and in jtop I can see the NVENC toggle on and off.

JTOP before running 7 camera nodes:

JTOP after running 7 camera nodes:

"Received an image, do you need to modify the code?"

Hello, what version of jetpack and Isaac are you using ? we have improved the CPU perf significantly on newer releases.
