Has somebody used an adapter with the Aquantia AQC111U chipset and had good performance on that? I tried that one here - https://www.delock.de/produkt/66088/merkmale.html?setLanguage=en - but unfortunately the performance was really bad. it was just half of what 1GbE nic can deliver... I've read that some of you have used the qnap usb nic. Has anybody ran iperf on that nic to check what the real performance is? I want to know if that nic is doing better although it uses the same chipset... Thanks.
