I just discovered I’ve been getting about half of the Ethernet bandwidth I should’ve been getting, and I’ve been let down by LG and Anker.
My setup is not trivial. I have a NAS in my detached garage connected to a UniFi switch. That connects over Fiber to a UDM Pro in the house. That connects to a UniFi switch under my desk over Cat 5E.
From there, it goes to my LG 5K monitor via an Anker USB-C to Ethernet adapter, and to my M1 MacBook Pro via TB3 (what the LG display supports).
I was measuring 433 Mbps to the NAS using iperf. I did some experimenting, and found that putting the Anker adapter right on my Mac increased that to ~720 Mbps.
That ruined the wonderful setup I had, wherein I only had to plug in one TB cable to the MBP to use my entire setup. So I dug into some storage boxes and pulled out an old OWC TB3 dock with built-in Ethernet. Plugged the MBP and display into that over TB3, got rid of the Anker adapter altogether.
Now I'm getting over 890 Mbps to the NAS.
I'm angry at all the times I had to wait for long file transfers recently. Transfers that could’ve taken half the time, because LG and Anker couldn’t keep up.
