64 queues costs a tiny amount more than 32 queues. If you can get it down to eight or nine queues with no actual cost (espcially for non realtime queues) then it represents a huge win since an 8bit ffz can be done by lookup table and that is fast on all processors - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
