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

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.
Is this with EM_INTR_FAST enabled also?
