I think the issue is resolved.  I had to recompile my 4.4.0 kernel with a few 
options pertaining to the Intel NIC which somehow (?) got left out or otherwise

those changes now in I see essentially identical performance with the two 
kernels.  Sorry for any confusion and/or waste of time here.  My bad.


Can you please send the relevant changes in the config that caused the 
discussed issue?

Just in the case other people do a similar kernel upgrade from 3.x to a 
recent kernel and the current defaults lead to this non-optimal result.

Thanks,
