Here's an example set of screenshots. Ran through world till lag, World is now empty, no trees, rocks, NPCs, structures etc.

20 seconds later some of the trees show up (haven't moved, facing same direction).

You can see telemetry information by pressing F2. Here's the data rate shortly after those pics. Note the client transmit rate is 59KB/s, 0KB/s from the server because it's still waiting for the bandwidth limited transmit from the client. Any DSL circuit will be hard pressed to sustain 60KB/s, and it's way over the bandwidth of a normal 10 or 15Mbit DSL circuit.
