Inference is slow while running with rtsp in ros(isaac)
is there anything need to change in config file for faster inference
below is the config file that iam using:**
[application]
enable-perf-measurement=1
perf-measurement-interval-sec=5

[tiled-display]
enable=1
rows=1

what is the GPU model? How did you observe that inference is slow? what the fps and resolution of RTSP source? please refer to this link for performance improvement.
