    RH has both of the above turned on in the
    2.6.32-71.29.1.el6.x86_64 kernel tested.

    If these are big negatives to network
    performance, could you list what should
    specifically turned off to maximize
    results? Also a recommendation for
    the best recent kernel for another
    benchmark would be helpful.

    Probably can't convince anyone to deploy a
    kernel without commercial support, but if
    an alternate compile fixes performance it
    might be possible to convince RH to support
    the alternative build.
