Ethernet ports super slow?? Mac Pro 2019 onboard LAN

Hey everyone,

Super disappointed spending over $10k on that Mac Pro.

I just tried figuring out what the heck is up with the onboard ethernet/Lan speeds since they're insanely slow compared to using a usb-c to ethernet adapter.

I can only get a 50mbit connection where I am so every MB/s counts.

When I used:

LAN port 1 it reached 20mbits

LAN port 2 it reached 20mbits

Belkin USB C to Ethernet adapter it reached 44-50 mbits

(just like the windows pc connected to the same ethernet)

All CAT-7 wiring has just been redone by myself and measures perfectly - zero issues on Windows PC via Ethernet. All my Ethernet advanced options are on auto (didn't mess with dns servers nor mtu etc.)

Don't know if firmware or drivers might be updated going up to Sonoma I'm currently using Monterey.

Any help appreciated!

Cheers!
