How to maximize bitrate on the jetson orin

from devs:

“We are seeing on 3gbps on the orin 10g port”

Any solutions?

Is it devkit or custom carrier board?
On JetPack 5.0.2 GA release?

it is the devkit

The devkit seems to have the original OS release.
What LAN throughput is supported for 5.0.2 GA release with devkits? Is there a way to get a figure closer to 10gbps?

The environment decides the result too.

For example, if I connect two jetson Orin directly, set MTU size to 9000, then I can achieve 9.8Gbps …

Thus, I cannot tell what you should try now. Maybe try with larger MTU size too.

like that?
sudo ip link set dev eth0 mtu 9000


Not 100% sure, but I think that further than both ends, any device in between if any would have to support Jumbo frames.
Check from one end with:

ping -M do -c 4 -s 8972 <other_end_IP>

Better start with direct connection as mentionned by @WayneWWW.

can we can test orin 10g in loopback somehow?

Well, I think I successfully experimented jumbo frames with lo interface. Default MTU size should be 65536.
Not sure it is a good advice, not tried with recent L4T releases, no idea if it can break something, but with caution you may try reducing MTU to 9000 on lo and check if nothing bad happen.
This would only test SW, going through ethernet HW may be different, though.
