Are there any kernel changes which could make my situation better ? The
preemptive kernel parameter or the MSI vector based IRQs ? Or even
vice versa, is it better to switch something off ? Or any other
kernel parameter ? I'd stand a lot if it just costs only 5% performance
but I want to stay in hyperthreading. Switching off hyperthreading costs
30-40% performance. :(
