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.
