Thanks David.
Would you mind giving me a bit of intuition why I can't have a 1:1
mapping of CPUs to NICs?
I am a bit out of my depth here, but I'd like to learn.
Best,
Don

It seems to me that with 4 independent NICs and plenty of CPUs to
spare, I ought to be able to assign one softirq daemon to each NIC
rather than funnelling all of the traffic through 1 or 2.
Traffic doesn't get distributed unless the NIC has support
for RX flow seperation and PCI MSI-X interrupts. Your NICs
do not.
So no matter how hard you try, each NIC is going to have it's
packets processed essentially on one cpu.
