It interacts quite excellently. There was a long saga about this with tg3 and huge SGI numa systems with large costs for interrupt processing, and the fix was to do a minimal amount of interrupt mitigation and this basically cleared up all the problems. Someone should reference that thread _now_ before this discussion goes too far and we repeat a lot of information and people like myself have to stay up all night correcting the misinformation and misunderstandings that are basically guarenteed for this topic :) - To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
