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.
