USB3 to gigabit ethernet speeds

I'm using a USB3 to gigabit ethernet adapter with my MacBook 2016 m3 and just recently had gigabit Internet installed.

Testing with various speed test sites the most I am achieving is 500-560mbits down. Now don't get me wrong - this is incredible speed - but I'd like to hit 850+ which is reaching the limits of gigabit ethernet.

Have others been able to use any gigabit ethernet adapters and achieve close to the full 940mbps of the gigabit ethernet spec? I don't have any other gigabit devices to test my Internet on at the moment so I can't confirm if it's an issue with the adapter or not. The connection from my ISP to the modem itself is connecting at 1.25Gbps.


Thanks,

Test on the intranet, not the internet. Too many variables for the latter.

That's what I would/will do when I have another fast gigabit device to transfer with. But has anyone here used a USB3/-C gigabit ethernet adapter on the Internet or their local network and achieved greater than 500-600mbit/s?
