Hi,
I try to feed 16 input sources using deepstream-app and test3 with the same config,same sources and same model engine file. My system configuration: ubuntu18.04 deepstream5.0 ,GTX1070. YOLOv3 Input image size is 320.
Deepstream-app as the following:

I found the different performance of YOLOV3 as primary-nvinference-engine when using deepstream-app and test3, deepsteam-app is about 50-60ms ,but test3 is above 200ms.To the point , the same cfg file, the same model engine file and the same sources.
Can you help me to investigate it. Thanks a lot.
