The best way to achieve such balancing is to have the network card help and essentially be able to select the CPU to notify while at the same time considering: a) avoiding any packet reordering - which restricts a flow to be processed to a single CPU at least within a timeframe b) be per-CPU-load-aware - which means to busy out only CPUs which are less utilized Various such schemes have been discussed here but no vendor is making such nics today (search Daves Blog - he did discuss this at one point or other). cheers, jamal - To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html
