    According to our empirical measurements using PF-RING (if that's
    what you are using), DON'T use CPU affinity; DON'T bind CPUs. Let
    the Linux scheduler do what it wishes..<br>
    The definite proof is to compare identical runs using different
    setups on your hardware, with your rules, with your traffic..<br>
    However, i would bet that what I recommended above will win..<br>
