Ok. Should the model name at least reflect one being a Xeon P4 and other as core2 Xeon? ;-> > The tuning required by the P4 is quite > different than the Core 2, and it generally performs more poorly due to > the length of the pipeline and the expense of pipeline flushes. I would be very interested to see some numbers on a proper Core2 based Xeon (unfortunately cant afford one). You have the hardware, what says you? ;-> AFAIT, the main reason Opterons has the numbers it does is due to the integrated on chip MC. I dont see Intel any time soon getting rid of that (for economical reasons more than technical). In any case i see batching as actually being a lot more cache friendly too. 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
