mentioned in first message disabling GRO in physical interfaces doesn't
improve the performance (step 5), only disabling TSO in virtual
interfaces causes a significant improvement. the problem with that is a
modification is needed every time an instance is launched.<br><br></div>Cheers<br><br></div><div>Alberto<br></div></div></div></div>
