Technical Details:
The adapter is based on the AX88179 chip company Asix, he has two LEDs, blue and red, which indicate Link / Speed and Aktivitiät.
I sit with a RHEL6.4 with the kernel 2.6.32-358.11.1.el6.x86_64. This does not provide a module for the adapter, but the driver from the manufacturer's website Asix compiles quickly and works flawlessly.
Performance:
About the internal Gigabit Ethernet port on my laptop to reach by iperf a transfer rate of 935MBit / s to my test server, which is quite close to the theoretical maximum of a TCP connection of 941MBit / s is an MTU of 1500.
Using the adapter (InLine USB 3.0 network adapter cable, Gigabit LAN, 33380B), I'm getting the same test server as a remote station, a transfer rate of 889MBit / s, which is fast enough for my purposes.
