Reborg,

Ur guess is right. its t1k.
I had tried it earlier and made it 4 each, but did not help. The driver seemed to be stuck on one VCPU and when the load increased we started losing packets.

I have tried the below settings too.
set ip:ip_squeue_bind=0
set ip:ip_squeue_fanout=1

But the driver seems to be having some cpu affinity(with or without creation of processor sets).

It does not budge. Any suggestions?

You could try increasing the number of rings.

If it's a t2000, you have e1000g nics, and I'm not sure if equivalent code has been putback yet.
