Hello, to record the sensors etc. we use a NFS based device which is attached to 10GbE RJ45 port of AGX. Device has also a 10GbE interface and has Samsung 860 pro SSD’s.
When we measure the write speeds with ’ dd if=/dev/zero of=/mnt/DEVICE/ bs=1G count=10 conv=fsync’ we could only achive ~250MB/s whereas with another 10GbE computer we achieved ~700MB/s thorughput.
Do you have an opinion why we have those kind of results and how can we improve AGX’s internal write speed’s (if this is the case)?

Dear @kaltinok,
Is it possible to use iperf/iperf3 to get some insights on the BW achieved in both cases? Could you share connection diagram like where you have connected on AGX?
