comment Why does traffic between two computers on a switch still travel through my router?
Yes, my assumptions were incorrect. A number of things happened, including a faulty cable, mistaking which cable goes where, the firewall being enabled on one computer, and a faulty backup disk.

Ouch. So my external backup drive was slow because it's starting to fail, data corruption and all that. That explains at least some of these issues.

I know that. I'm thinking Megabytes, not Megabits.

comment Why does traffic between two computers on a switch still travel through my router?
Ok, so file transfer speed is still below < 40 MB/s after changing cables (though ok, might be limited by the R/W speed of the 2.5" disks), but Time Machine is still extremely slow over the network. I'll look into that, perhaps its a TimeMachine specific issue. With the new cable at least I can see clearly on the switch's ports that by far most traffic is switched directly, because the router's port blinks less frequently.

aaah … interesting: one Mac to the other is all asterisks, vice versa it's a single hop as it should be. Checking firewall… yes, the target computer had its firewall enabled (from wayyyy back when).

comment Why does traffic between two computers on a switch still travel through my router?
yes, but I only get asterisks for all hops. I also found out that one of the network cables was faulty and connected only at 100 Mbit/s. After exchanging it file transfer speed went up, though time machine from one mac to the other mac's shared drive is still very slow.

comment Does All LAN Traffic Travel Through A Router
It's not true in my case. I have a router (192.168.1.1) which also serves as DHCP server. My two Macs are on the same 5-port switch, which also connects to the router. If I unplug the router cable, I lose all internet connectivity (to be expected) but the two Mac also stop being able to access each other! Yes, I'm using a switch and not a hub, and I've seen it work as it should before - just not in this setup.
