I’m curious how close your total throughput would be to the theoretical 10Gb/s, assuming it was used with a switch that could keep up. Protocol overhead with Ethernet/TCP/IP is bad enough without NIC teaming to say nothing of the total throughput of the Thunderbolt transceiver

I don’t know if I’ll remember, but I’ll be able to try this in a few days, I have the same laptop, 2x 2.5G USB NICs + another 2 already in the mail, and also a 10G network.

If you’re wondering, my intention for ordering them definitely wasn’t for this, but more just for places around the house I can plug into, without having the framework NIC hanging off my laptop.

Alright, so testing with iperf3 to a 10G host:

  • Single Direction - 7.06 Gbps RX (2.35, 2.35, 1.25, 1.11 Gbps individually), 9.4 Gbps TX (All 2.35 Gbps)
  • Bidirectionally - 8 Gbps Total, 1.538 Gbps RX & 6.55 Gbps TX (315/1220, 232/2080, 256/1520, 735/1730 Mbps individually)

4x USB NICs on the laptop, 1x Solarflare SFN5122F NIC on the desktop, there were 2 10G switches in between which may have affected the speeds slightly.

Also I can get 4.6 Gbps total (2.3/2.3) bidirectionally on one interface, so I would have expected ~16 Gbps with 4, so that’s interesting I guess? My desktop can do 18.6 Gbps total (9.55/9.11) to my server so idk.

Edit: I was using 1500 MTU, I don’t feel like testing again with jumbo frames.
