        they are 4-core xeon e5420 - you can say this machine is a 20-core computer. That is why it beats the hell out of everyone's RAC.

          Xeon 5420 has no HT and does not support more than 2 physical CPUs (resulting in a total of 8 cores).

          It might be some virtualisation thing if the operating system sees more, or he is using a small patch for the core client because some project doesn't give him enough work (this is what I believe he has, the benchmark result looks not really calculated, more like a configured value). The benchmark values are not high though, that box would even have higher values if it did calculate the benchmark

          His RAC is realistic for this box, not looking weird to me.
