Xavier packet loss

LS128 lidar is conneted with xavier, 1 Gbps ethernet port. It send 1206 bytes udp data per 67us. The bandwidth is enough.When use ros send packet, it lost some packets.Tcpdump sometimes 330ms no packet data. when use a socket code to receive the data, packets are almost not lost.The orin soc is ok. the net.core.rmem_max of xavier and orin is same.The perfomance of xavier is Insufficient?

Sorry for the late response, our team will do the investigation and provide suggestions soon. Thanks

For getting optimal performance, please execute sudo nvpmodel -m 0 and sudo jetson_clocks. See if there is any enhancement.
