axge info

I'm experiencing performance issues with a USB 3.0 adapter using ASIX 88179 chipset [1], that should be supported by "axge" driver [2]

Basically, speed is not above ~530Mb/s, even though the device is correctly recognized as Usb 3.0 if running an iperf3 client test, while it's ~180Mb if running a iperf3 server on the machine and trying to connect from a Linux client.

If trying to use Debian 9 on the same machine, I'm not experiencing any issue, like described in this forum thread [3]. 

You can find more details attached to this post.

Please let me know if there's any further info I should provide.

Thank you.
