@arh @tyil 3MiB/s is slow as molasses considering that the >30 year old 100BASE-TX standard had ~11MiB/s throughput (full duplex usually, although some half-duplex hardware exists) and 25+ year old 1000BASE-T standard has 125MiB/s throughput (full duplex).

10GBASE-T is overkill for a typical home network and even that's >23 years old.
