Sucks. That card just doesn't perform under load (which you will
probably never reach).

Duplex is the transmission mode.
Half duplex means that only one channel will be active at any time,
either recieving or transmitting.
Full duplex means that you will get simultaneous transmission and
reception of signals.
Full duplex is generally faster, but has some limitations under heavily
loaded networks (packet loss isn't detected that readily at the ethernet
layer).
