Hi @metarefl ,
In the three cases (your app, deepstream-test3, deepstream-imagedata-multistream), seems only your app is affected by different pyds seriously (250 vs 140) while the others two have much less perf drop, right?
Is your detection running with TensorRT backend?
Is it possible for you to narrow down which components cause the perf drop referring to DeepStream SDK FAQ - #12 by bcao ?
