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.
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.
Fascinating, especially that the RX direction saw such varied speeds across the various NICs. Guess that switch wasn’t too keen on trying to split the packets evenly. Also – 1.5Gbit RX in bidirectional mode? …all I can say is yikes.

Yeah probably, I was just using one of those cheap 2x 10G + 4x 2.5G switches that ServeTheHome recently did a video on, so I would not be surprised if that was the bottle neck here.
I could maybe try buying a few more SFP+ transceivers and using my more trustworthy switches, but that seems too expensive for a project like this.

I’m invested now. Definitely report back!
Same
Alright, so testing with

Very good to know.
