I’m encountering network bandwidth issues with my 64GB Orin dev kit connected to a high-end desktop. My end goal is to be able to transfer data via the 10Gbps link from the dev kit to the desktop via NFS. I’m noticing that I’m somehow inducing conditions that reduce overall throughput and seem to …

I don’t see how this would address what I’m running into. I think zero-copy is a different issue altogether. I can achieve 9.9G not using zero-copy. A problem gets introduced if one “fixes” the mac-sec issue in the kernel and can actually set the MTU to 9000. The MGBE starts encountering mgbe_pa…

FWIW, I inserted a X540-10G-1T-X8 10GbE adapter into the Orin dev kit’s PCIe slot and ran the iperf3 tests against the TOE mode of the Chelsio adapter. Results: iperf3 in standard mode w/TOE: ~$ iperf3 --client 10.0.3.1 Connecting to host 10.0.3.1, port 5201 [ 5] local 10.0.3.11 port 39974 conne…

I’ve noticed that I can get the problem to go away if I disable tx-checksum-ipv4. The side effect of doing this is decreased throughput. Here are the steps that I follow: Reboot the Orin dev kit Reboot the desktop Leave the desktop’s Chelsio adapter in the default “NIC” mode Configure the Chelsi…

It seems that the patch I created to allow a packet size of 9000 (see RGMII issue with Jetpack 5.1.1 (KSZ9131) - #7 by waterbear ) is inducing the issue. I decided to try different MTU sizes to see what effects those had (e.g. 1500 → 3000 → 6000 → 9000). At 9000 the troubles appeared. I backed thi…

Reduced bandwidth at 10Gbps on Orin and mgbe_payload_cs_err correlation

Hi,
Please try this setup:
The maximum speed of the 10G network port of the ORIN-32GB module can only reach 6.5G using iperf3 - #4 by DaneLLL

The rootfs wirh Ubuntu desktop may have impact to throughput. Please try minimum rootfs.
