However, if I turn on fastforwarding, its back to the old behavior

#define EM_FAST_INTR 1
as well as taking out the nfs option from the kernel
driver. Anything else to tune with ?

Would you mind going so far as to adding NO_ADAPTIVE_MUTEXES? This is
Wow, it totally survives 2 streams (2 in one direction or 2 in
opposite directions)... AND it almost can survive a 3rd! It does seem
to be dropping packets on em1 when I add in a second stream blasting
in the same direction, but its survives. You can see at ** I add in
the second stream, and the outbound on em1 drops, even though more
packets are going through. I stop the second stream then add a
stream going in the other direction. Oddly enough, with a UP kernel
it cant do 2 streams, just the one. I thought the extra locking on
SMP would make it worse ? In this case it seems no.
