Hi Chuck,

I have no answers, just a few questions for comparison.  (1) Are you 
seeing "IRQ nobody cared" messages on local interfaces? (2) Are your 
interfaces using RealTek eth controllers? And, finally, have you done 
any network performance tuning? i.e. tweaking parms like 
net.core.rmem_max?

Thanks
