The reason you're getting such poor performance when you configure the adapter in full-duplex mode is probably that the device into which it is plugged is configured to run full-duplex. When you configure MacOS to run full-duplex, it *says* it's full-duplex, but it's actually running in half-duplex.

I discovered this the hard way on Monday when I tried to transfer 80g of data over a crossover cable. The only way I was able to get decent performance out of the connection was to configure both ends half-duplex. If I configured both ends full-duplex, performance was about what you're reporting.

Sigh.
