I am sure, we all will be glad to hear about this "valid" comparison. So
far, I have not seen any reports on the performance of dual-core dual-CPU Xeon
servers. Thus, I am reporting the data I got by running the machines that
are available to me.

If you have the dual-core dual-CPU Xeon data, please post! Then, everyone
will decide for him/herself what's faster/better/cheaper.
