Do you have tso on/off? I suspect youd see better numbers with tso off. > Batched xmit has better numbers. Much appreciated.

I think the benefit would be a lot more visible as the number of flows goes up (simply because there will be a lot more packets/sec going into the driver). 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
