> A speedtest shows that it can at least do 90Mbps (one of my dongles is only 100Mbps).

Would be interesting to see if 90 is a bottleneck of the machine, or if a gigabit connector would let you go faster.

It’s not a long read and likely worth your time, but the TL;DR is turning a Switch into a network switch. Not a very fast switch, but it’s amazing that the pig sings in the first place.
