agx xavier device omxh265dec and nvv4l2decoder decoding performance is worse than Windows d3d11h265dec ?

The capability of hardware decoder and encoder is listed in

Generally we compare Jetson platforms with other embedded platforms. It is possible the performance is worse when comparing to host PC. For example, running a CUDA application shall have better performance on desktop GPUs than Jetson platforms.

My goal is not to compare, but to get Windows performance on the agx device.The agx xavier platform couldn’t find a way to improve performance.
Cuda can be added to the GStreamer Pipeline to improve performance?
Cuda can be used to realize low delay receiving RTP/UDP stream decoding and playing?
