Subject: RE: Poorer networking performance in later kernels?

> 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 clobbered when I ported my 3.4.2 .config to the 4.4.0 kernel source tree.  With 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,
Oliver

Yes I just replied to another email on this thread asking the same thing and posted some info.

Cheers,

Peter
