I’m trying to get the default ubuntu OS to forward packet at 1Gbps between the default eth0 to an USB-to-Ethernet adapter (USB 3.0, 1Gbps). I’m consistently getting around 90Mbps using speed test. When I am direct connected I was able to get around 200Mbps or more. I’m wondering if there’s any bus limitation here? is the USB 3.0 really capable of 5gbps?
eth0: negotiated 1000baseT-FD flow-control, link ok
eth1: negotiated 1000baseT-FD flow-control, link ok
