Does USB ethernet adapters have a lag comparing to standard Ethernet connection?

No, it shouldnt. USB uses the CPU so that should be the only hit but there should be no difference in noticeable performance. I just hate that companies arent going all in for 10GbE I wont upgrade my router or anything till everything is 10GbE. ive had 1GbE since 2005....

Thanks. Are you missing something by not going up to 10GbE? I have 100mbit connection (provider and lan) and never thought I'd need more speed. Just letting heavy data download overnight.

well they cant over USB 3.0, the requirements for full 10GB nic is at least Thunderbolt 2, and Network cards for PCs are cheap but decent 10GB switches are still pricey for it to be mainstream.

Having had my fair share of laggy USB peripherals I sincerely doubt your assessment is correct. I don't know enough about the subject, but having had pricey accessories that would show input lag of over 200ms your "NO" should come with some caveats. On a separate note, why go 10GbE? Besides the fact that you can get it now if you're willing to pay for it. It's not worth it for the average consumer. 10GbE would easily overwhelm a SATA SSD, so without NVME or RAID everywhere it would be pointless for storage transfer. Considering the price decrease for RAM, you could use apps that keep all they crap in memory, but apart from a smaller delay when doing extremely heavy loads you wouldn't notice anything. From what I know, the only thing the "average" person might be doing that would benefit from 10G is high res video editing, but that's already stretching the definition of "average" to the breaking point.

Can somebody with this adapter please post a iperf3 benchmark result? Thanks in advance!
