The solution posted universally was 'change >card'. Yes, that *was* the common recommendation. But recently I narrowed down the realtek performance problem most commonly seen with samba (but also applicable to other TCP applications), and I also narrowed down the fix as well. The current fix involves re-kicking the TX queue after it becomes stuck. Apparently it becomes stuck due to a contention problem between the driver and controller. I suspect the root problem is the driver isn't properly locking the TX queue. It might be worth checking if the queue locking problem exists in other net drivers as well.
