It seems so. As I mentioned earlier I havn't seen irq balance option in recent kernels. Static irq2cpu assignment works well (even on HT processors). > While searching the web, I found reports about big performance > increases in 3D rendering due to disabling the feature. Can this be > true and why? I don't have a clue. I can say one thing - static irq2cpu assignment worx4me on linux routers hauling 400+kpps. Without it only one core/processor would be used. cheers, Marek Kierdelewicz _______________________________________________ LARTC mailing list LARTC@xxxxxxxxxxxxxxx http://mailman.ds9a.nl/cgi-bin/mailman/listinfo/lartc
