Does he have 10G at home yet? That still seems short of what you'd need to get a 255MB bandwidth-delay product. I'm just curious what the experiment is here and whether there's a possibility the real problem is elsewhere. In my opinion, any fix that involves allocating multiple parallel data streams (rpc slots, tcp connections) is masking the real problem. But it's an effective fix. -- To unsubscribe from this list: send the line "unsubscribe linux-nfs" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
