Wouldn't you saturate the bus fairly easily with a Mellanox card?

I can't imagine the experience would be optimal.

From all my testing, it looks like the maximum throughput you can get on the entire PCIe x1 gen 2 lane on the CM4 is about 3.2-3.4 Gbps.

But that's still better than the current maximum of 1 Gbps over Ethernet, or the ~3 Gbps I have tested through a USB 3.0 card.
